I'd suggest learning basic as well. Then you have most languages covered.

I've never tried real Java nor smalltalk so I'm afraid I can't comment on
this

I guess it's a matter of opinion

Really? Always thought it was char. But how many will notice the difference?

Is it? Didn't know it was legal with such init's.

I must say that this code looks so weird you can't have it working. Not even
GNU wants to have
anything to do with it (read the specs yesterday :)
