ralph hypothesized:
My imagination suggests to me that in a
typical short perl 6 script, between 20%
and 50% of all sub defs would use the
upscope topic... ;>
That's some imagination you've got there! ;-)
My estimate (based on the -- not inconsiderable -- code base of
my own modules) is closer to 5%.
But that's beside the point. The two factors that nix this idea
IMHO are that:
* Putting a non-parameter in the parameter list
is Just Plain Wrong
* Using a single character to denote the use of
an upscope topic is insufficiently obvious
(regardless of which character is used for
the purpose)
