Lambda the Ultimate

Can someone help me decode this comment from this post on Scala type inference:

On the other extreme, it is *possible* to do constraint typing in a nominal type system with subtyping, but you have to give up entirely on separate compilation. Type checking effectively turns into a special case of control-flow analysis, which not only makes the whole process exponential, but also completely kills the idea of reusable APIs and separately distributable libraries, since the entire program must be available to the type checker in order to definitively derive the union type at a particular declaration site.

Is that a theoretical result published somewhere? And when they say constraint typing, they mean "constraint-based typing" right?

/************************************************************************************/

The ACM SIGPLAN conference on Systems, Programming, Languages and Applications: Software for Humanity (SPLASH) embraces all aspects of software construction and delivery to make it the premier conference at the intersection of programming, languages, and software engineering. SPLASH is now accepting submissions. We invite high quality submissions describing original and unpublished work.

** OOPSLA Research Papers **
Papers that address any aspect of software development are welcome, including requirements, modeling, prototyping, design, implementation, generation, analysis, verification, testing, evaluation, maintenance, reuse, replacement, and retirement of software systems. Papers may address these topics in a variety of ways, including new tools (such as languages, program analyses, and runtime systems), new techniques (such as methodologies, design processes, code organization approaches, and management techniques), and new evaluations (such as formalisms and proofs, corpora analyses, user studies, and surveys).

Submissions Due: 25 March, 2015

** Onward! Research Papers **
Onward! is a premier multidisciplinary conference focused on everything to do with programming and software: including processes, methods, languages, communities, and applications. Onward! is more radical, more visionary, and more open than other conferences to ideas that are well-argued but not yet proven. We welcome different ways of thinking about, approaching, and reporting on programming language and software engineering research.

Submissions Due: 2 April, 2015

** Onward! Essays **
Onward! Essays is looking for clear and compelling pieces of writing about topics important to the software community. An essay can be an exploration of a topic, its impact, or the circumstances of its creation; it can present a personal view of what is, explore a terrain, or lead the reader in an act of discovery; it can be a philosophical digression or a deep analysis. It can describe a personal journey, perhaps that by which the author reached an understanding of such a topic. The subject area should be interpreted broadly and can include the relationship of software to human endeavors, or its philosophical, sociological, psychological, historical, or anthropological underpinnings.

Submissions Due: 2 April, 2015

** Workshops **
The SPLASH Workshops track will host a variety of high-quality workshops, allowing their participants to meet and discuss research questions with peers, to mature new and exciting ideas, and to build up communities and start new collaborations. SPLASH workshops complement the main tracks of the conference and provide meetings in a smaller and more specialized setting. Workshops cultivate new ideas and concepts for the future, optionally recorded in formal proceedings.

Early Phase Submissions Due: 25 March, 2015
Late Phase Submissions Due: 30 June, 2015

** Dynamic Languages Symposium (DLS) **
DLS is the premier forum for researchers and practitioners to share knowledge and research on dynamic languages, their implementation, and applications. The influence of dynamic languages — from Lisp to Smalltalk to Python to Javascript — on real-world practice, and research, continues to grow. We invite high quality papers reporting original research, innovative contributions, or experience related to dynamic languages, their implementation, and applications.

Submissions Due: 7 June, 2015
