nope, the real problem is that @matches = (1) if it matched without capture groups in $re

new attempt:

    
    if ( my (@caps) = ($line =~ $re) ) {
        @caps = () if $caps[0] ne $1;           # reset pseudo capture
+s
        $cb->(@caps);
        last;
    }

Full backwards compatible and no performance penalty.

OK?
