It just occurred to me that many Perl functions use $_ if not other value is supplied. chomp for instance..., which is very handy...
If one wanted to write a function that used either the given argument or $_ how would you do that?
myfunc($myvalue); or myfunc; #uses the current value of $_
sub myfunc {
my $func_arg = shift || ????; # you wouldn't just do '|| $_;' would you?
...
