I think that's already whatever context. $x contains the resulting array.
It's only if you later say +$x that you'll get the number of elems.
Just for grep or for any function
Hi...
I think that Perl 6 should have a whatever context, which is
essentially:
I want either array or scalar or whatever... You choose
so that functions like grep can return an array in whatever
context. This is best demonstrated using an example:
my $x = grep { ... } @list
