Well, of course you run the danger of making it hard for people to
recognize labels which are otherwise common across many languages, but
here's a few ways you could do labels if you need to:

The real problem is that you're using a trailing glyph to identify what
is essentially a type, so you could introduce a leading glyph:

        rx/: <identifier> <ws>+ ( <statement> | <control> ) /

Is there ever a reason for a leading adverb in a statement or control

or you could have a keyword that introduces the label:

        rx/label <ws>+ <identifier> <ws>+ (<statement>|<control>)/

or you could use some kind of trickery:

        rx/label : $/

note that this means that we're making a newline part of the syntax,
which might feel "too python" to folks (especially where it ends in a
":"), but it would leave you with very P5 looking labels:

        while =<> -> $line {
                for split('',$line) -> $char {
                        next CHAR if $char eq ' ';
                        next LINE if $char eq '#';

Of course, let leaves you not able to do:


And I'm not even going to start on the "if it's the same column"
thing... ;-)
