in thread Favorite programming language, other than Perl:

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' :-).
