in thread looking for a good idiom: return this if this is true

Aha! I knew it merely took the electron spin reversal of the other side of the world to solve this correctly! Thanks. That's the version that goes into the example now.

    This works fine, and does not clobber $_. 

    #!/usr/bin/perl -w

use strict;

print test(), $/;

sub subtest { return 4 }

sub test {
    return $_ if ( local $_ = subtest() );

    # continue
    return 'false';
}
