I just wrote this little module. The problem it tries to solve is the following.

I have a set of packages, each of which specifies a part of the behaviour I need. The idea is to be able to exchange one specification with another (for those who know, I'm translating an ASM specification).

I wrote the subs in the packages to be used as methods, and one of the packages defines new, but this is not really relevant...

What I can do is something like:

 package a;
 sub sa { return 1 }
 sub sb { return 2 }

 package b;
 sub sb { return 3 }

 package main;
 use Class::Merge qw(b a) => 'c';

 $r= c->sb();  # returns 3

This, coupled with NEXT, gets me the result I need.

Now I ask:

• Is this useful to anybody else?
• Might it be worthy of CPAN?
• I currently call it Class::Merge, but since it doesn't really involve classes, what could be a better name?

Oh, the whole module boils down to:

sub import {
  my $dest=pop;
  shift;
  eval <<"EOF";
package $dest;
\@${dest}::ISA=qw(@_);
EOF
}
