Trey Harris asked:
This is eerily like Contextual::Return, which made me wonder if it's
even required in Perl 6.
Obviously we can do
return do given want {
when :($) { ... }
...
};
But "return do given want" flows so badly, I desperately want some sugar
for this. Is there some and I missed it?
No, the sugariest you'll find at the moment is probably:
return want.rw ?? $lvalue
:: want.count == 2 ?? (7,11)
:: want.item ?? 42
:: want.list ?? 1..10
:: die "Bad context;
but that still doesn't have the Awesome Power of C::R. ;-)
The simple answer is that C::R is probably the first module I will port to
Perl 6 (since it's the module I find myself using the most nowadays). The Perl
6 version will be cleaner and more efficient that the Perl 5 version, since
I'll be able to take advantage of macros.
