in thread Favorite programming language, other than Perl:

Re passing blocks: thanks. Got that part working.

But about the other, I probably need to clarify a bit. The example in the doc was the following:

def a   print "Function 'a' called\n"   99 end for i in 1..2   if i == 2     print "a=", a, "\n"   else     a = 1     print "a=", a, "\n"   end end
Which prints:
a=1 Function 'a' called a=99
Frankly, I think that's perverse, and object-orientation won't save you. What if, instead of printing, you'd tried to call "a.blah"? Presumably you'd get the same sort of bizarre results.

    Sorry, you missed my point. Maybe some code will help. :-)
    class Foo def a puts "Function 'a' called" end end foo = Foo.new (1..2).each do |i| if i == 2 print "a=", foo.a, "\n" else a = 1 print "a=", foo.a, "\n" end end
    which prints:
    Function 'a' called a=99 Function 'a' called a=99
    You see, functions are meant to belong to a class -- to be methods. Not that you can't declare functions that belong to the main class, but that's not what the design was for. So I guess if you're writing your code in a non-OO way, you could get stuck. But presumably your variable and function names will be better than 'a' :-).
