in thread Massive expansion of a hash of arrays?
A final point, i tried to move the subroutine definition below the code calling it (I like to keep all my subs at the bottom), but i get an error: Can't call method "nForX" without a package or object reference at ./test.pl line 617.It seems you'll need to add a forward declaration with the prototype in order to move the sub definition below the calling code.
sub nForX(&@); ... nForX { print join ' ', @_; } 3, \( @a, @b, @c ); ... sub nForX(&@) { #use of prototype here is actually irrelevant #now, i.e. sub nForX {...} works the same ... }
