Is there a better way? Any reference to the cases where it will fail?

    It will fail on this:
    my $increment_by_secret = do { my $secret_number = 7; sub { $secret_number + shift }; };
    It fails because there's no access to $secret_number from outside the coderef, so we can't tell what the "magic constant" should be. All you get is:
    { ($secret_number + shift(@_)); }
    (Just tested.)
