Probably, though maybe not with that exact syntax.

Well, I've never heard of @array.assuming, but I suspect if the
PDLers want something like that, it wouldn't be hard to sneak it in
at some point. We're giving them plenty of rope to hang themselves
and everyone else too.
That being said, you're using .[0;;0] as some kind of a noun when
it should mean $_.[0;;0], and that's not gonna be considered very
Perl6ish. Besides, you seem to be using 0 to represent one kind of
wildcard, and a null slice to represent a different kind of wildcard,
and the array itself seems to be varying between three dimensions
and two. I doubt that's the syntax you want for mapping one array
onto a subset of another.
