The ruby one liner:

	(foo ||= {})[obj] = 'hello'

Autovivification is convenient, but can also lead to unnoticed bugs, 
for example, the misspelling

	fool[obj] = 'hello'

would not be detected.

Please no. C loops are ugly. for(a; b; c) gives no indication of what
a, b and c means. Of course, you learn with time, but you shouldn't 
have to.

5.times, 1.upto(10) is much cleaner. Use while loops for anything
more complex. It makes the code easier to read.

This would be nice, but it requires hacking the parser, which (as far as
I understand) is already a complex beast. At least "25 < x < 75" raises an
exception in Ruby. It doesn't silently give the wrong answer (as in C).
