Lambda the Ultimate

I suppose there's the possibility that having the keywords in one's native language can also be a disadvantage, as words (like class, object, function, etc...) tend to have more than one meaning outside of the programming language - messing up the connotation.

There is another "advantage" in that you can use words from another language for variable names. This may seem useful when the English word conflicts with a reserved word. Personally I don't like this practice, though it might be useful if I could use Hebrew characters instead of typing the word using Latin characters.

Now the code can only be understood by Hebrew speakers?

Ugly, ugly, ugly!

Definitely, that's why I said I don't like and have personally never used it. Indeed I've only seen this done by some University students and in the army (where you obviously only expect the code to be seen by Hebrew speakers).

By the way, the tutorial is now available online. I'd be grateful if someone tries to download, since I need to know if it is indeed publically accessible, and that the Hebrew titles etc. on the download page are not causing problems for browsers that don't support Hebrew.
