Map instead of Hash from sub EXPORT results in missing error about non-dynamics via CALLER::

[zoffixznet]

I believe the first eval needs to throw just like the second does:

<Zoffix__> m: BEGIN '/tmp/dyncall'.IO.mkdir.add('DYN.pm6').spurt: ｢sub EXPORT { Map.new: ('$meows' => 'foos', '&foo' => sub { CALLER::<$meows> }) }｣; use lib </tmp/dyncall>; use DYN; say foo
<camelia> rakudo-moar 6a6470f9d: OUTPUT: «foos␤»

<Zoffix__> m: BEGIN '/tmp/dyncall'.IO.mkdir.add('DYN.pm6').spurt: ｢sub EXPORT { {'$meows' => 'foos', '&foo' => sub { CALLER::<$meows> }} }｣; use lib </tmp/dyncall>; use DYN; say foo
<camelia> rakudo-moar 6a6470f9d: OUTPUT: «Cannot access '$meows' through CALLER, because it is not declared as dynamic␤  in sub  at /tmp/dyncall/DYN.pm6 (DYN) line 1␤  in block <unit> at <tmp> line 1␤␤»

I think the problem here is that dynamic is presently a property on a Scalar (or Array or Hash). When CALLER lookups encounter something that does not have a dynamic method, it just resolves the result. We can't just make that case throw, alas, because we'd break every case like my $*FOO := 42 - that is, where binding was used.

Also, to be clear, I'm not saying this shouldn't be fixed, just that there's not an immediately obvious way to do it.
