In r33954 this succeeds in Rakudo​:

my %hash; %hash<foo> = 'bar'; say %hash<foo>;
bar

but this fails during PAST->POST​:

my %hash; %hash<foo> := 'bar'; say %hash<foo>;
rtype not set

This worked fine as of r33837.

The addition of the capability to do array and hash slices has
cause binding of array and hash elements to fail. I decided
that slices and list assignment were more important right now
than binding elements of aggregates, so we've regressed there
for now.

I don't see a short-term fix on the horizon, as we'll have to
figure out exactly how we're going to handle such bindings/references
in the future. Parrot isn't exactly set up for handling this
easily in a HLL like Perl 6, I'm afraid.

Are any virtual machines?

(Is there one that Parrot can steal ideas from, I mean, imitate.
Er, I mean flatter)

Modulo the exact syntax, I'd expect the answer from Rakudo to be more
like the one from Pugs.
