No. length(@b) or @b.length() for that.

Yep. Scalar context eval of arrays, hashes, and subs produces a reference.
> 3. Get the first element of @b
No. That's still:
($a) = @b;
...which may well grab *only* the first element, because the lvalue's
structure determines the rvalue's eval context (just like a sub's
parameter list determines its argument's contexts)

This one's still less-than-certain. Definitely either 1 or 3 though.
If option 3, it would be the equivalent of the Perl 5:
%c = map {($_=>undef)} @d;
