Well.  The way blocks and iterators are used in ruby is not like it is
in perl (I don't know python very well but I don't know of anything like
that.

for example:
myObject.each { |x| puts x }

How would that code look in perl(6) or python??  The normal way of doing
it is

for $x ($myObject.to_printable_array)
{
  print $x."\n";
}

that code differs alot between the languages.  Ruby uses alot of
iterators and I don't see how they can be used from other languages.

How would the each-operator of myObject look for example ???

 
I'm sure it's solvable, I just don't know how?

Why??  I think ALOT of people here are interested.  I know I am.

btw, is perl6-internals the list for parrot-stuff??  Even if they are
ruby-questions??
