Surely that's the form that folks will actually want?
With no supporting data at all I'm going to claim it's reasonably common
to want to filter an array without any need to keep the original around;
having the Perl 6 idiom for that involve a temporary array seems rather
ugly, exactly the sort of awkwardness that Perl 6 is eliminating
elsewhere.
