How should that be implemented? I think this should work just like all forms of the built-in
chomp except it should remove more than trailing newlines. However, the argumentless form doesn't seem to work (doesn't propagate the lvalue context on the caller's
$_) as I would expect it should. What's the right way of falling back to the caller's lvalue
$_ if there's no arguments?
sub trim
{
@_ = ($_) if not @_; # doesn't work
foreach (@_)
{
s/^\s*//;
s/\s*$//;
s/\n\z//s;
}
return wantarray? @_ : $_[0];
}
