Indeed... Though what I'm wondering is, is there a hidden
implementation
cost or design cost of making /<foo>+/ always behave such that
$<foo>.from
returns something, compared to the current treatment with the
workaround
you suggested?
Has this been settled or addressed off-list?
'fraid not yet...
Because from my perspective as one who has never used P6 rules for
anything
in particular, but who in the future most likely will, the proposed
semantics seems a lot saner and more useful. It'd be sad to let pass
this opportunity to fix (what from my perspective appears to be) a
shortcoming of the rule semantics.
*nod* The lack of .from/.to is merely an annoyance, but the spaced-out
stringification is really, really surprising with /<foo>+/.
Thanks,
Audrey
