If the code is the first argument, you can use a prototype starting with '&', like this:

sub mymap(&@) { ... }
/s

    Damn, i want to use it as the second argument....

    guess i'm out of luck then ?

      Yeah. This one has bothered me, too. I suppose you could do something like this (untested):
      sub is(&) { return $_[0] } sub goal { ... } # ... goal 'foo' is { ... }
      but it's not quite as nice. Option 2: write a source filter that takes
      goal mygoal
      and replaces it with
      goal 'mygoal', sub
      That might be a good way to go.

      /s

        Thanks for the tip, I used Filter::Simple, and it seems to do the trick :-)
