try and do something useful with them.
We hates attributes, we do.

memoized logged (to => $file) sub incr (Int $i) {
$i + 1;
}
?
We can certainly decorate 'method' like that. Not sure if it's possible
with sub; when rafl took over trying to make sub signatures work I kind of
forgot most of what little I'd worked out about how 'sub' is parsed in
statement form.
Better still, how about we shift off to the perl5-syntax list and stop
bothering p5p until we have something worth shoving into core? :)
