( #3333=superdoc: print w/replies, xml ) Need Help??

Hm. My first reaction is to consider the possibility of:

my $x = foo(1,2,3,5);

This should of course be a scalar result, and not equal to scalar (@x = foo(1,2,3,5)). I'd feel uncomfortable omitting the results from the 2,3 and 5, so I'd probably do one of the following:

return wantarray ? @arr : "@arr"; return wantarray ? @arr : \@arr;

depending on use, 'yadda'x3. Perhaps, if it really suits the particular sub, you might want to return a join, but I'd personally be leery of that.
