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' :-).
