What's a better way to validate an array ref than "if( 'ARRAY' eq ref $foo )"? Thanks!
There are caveats whichever way you do it, but currently I tend to default to just derefing it within an eval block:
if (eval{ use strict 'refs'; @$foo; 1 }) {
# it is, or pretends convincingly, to be an array ref
}
Caveat? Right.
In the presence of ties or overloading, there may be side effects to derefing it. Pick your poison / buyer beware / etc.
print "Just another Perl ${\(trickster and hacker)},"
The Sidhekin proves Sidhe did it!
