Re^3: Question about regex performance

[choroba]

OK, "wrong" was probably a too strong word (I'm not a native speaker of English). But compare the following two expressions, both being "right" from the test driven perspective:

    # 1
    $x = 'a' . $y . $z->[1];

    # 2
    $x = join q(), scalar(chr 97), $y, (@$z)[1], '';
