hmm,
if I do this:

sub x
{
  my $window = GTk2::Window->new;
  ...
  $window->show;
}


the $window variable is unreferenced and might get GCed at any 
time (won't it)? 
It may be bad style to code thtat way but I don't  think I like 
the supprise of the window disappearing when a perl variable get 
garbage collected.

I also think Daniel's suggestions about structs has it point
don't be afraid to refactor solutions that are not good.
Some struct may just as well implemented as hashes (if used
mostly from perl) and some would be better of in native format
(those created soley to be passed to libgtk+)

Also string where mentioned earlier,
Daniel is right in that using g_strdup as I
have done in a few palces is not too clever.
Better to copy it into a SvPV so perl can GC it.

It is late, and I probably missed something or 
misinterpreted some statement but that my 2 cents
for tonight.
