Following up on (True|False) vs Bool::$!

This is a Rakudo issue, which I found while following up on the p6l thread
about literals.  I'm not sure where the best place to ask about it is; I
already said something on p2.  I will be happy to open up an RT, but I'd
like to understand what's happening so I'll have better luck making sure
it's not a dupe.  Maybe I'm just getting too far ahead of the development
curve in terms of what I expect to work at this point.

Basically, "True" and "False" are acting weird.

I thought they were simply aliases for their fully-qualified brethren
Bool::True and Bool::False.  Is that supposed to be the case?  It is true in
pugs, FWTW.

But in current Rakudo they seem to be distinct objects:

$ perl6 -e 'say (True === Bool::True).perl'
Bool::False

... and oddly lacking in identity and metadata:

$ perl6 -e 'say True.WHAT'

$

I thought the empty ".WHAT" was interesting, so I tried this, too:

$ perl6 -e 'say True.WHAT.perl'

$

I didn't think any .perl method would return nothing, but apparently
Object.perl does, and nothing is overriding it in this case.

The overall effect feels like an object-vs-primitive dichotomy, with
broken/partial autoboxing.

Also, as I said in the original message to p2, even though True.WHAT.perl
succeeds in producing an empty string, this fails spectacularly:

$  perl6 -e 'say True.perl'
Method 'perl' not found for invocant of class ''

Segmentation fault

Suggestions on next steps?  Assuming I have the problem properly identified,
I will be happy to submit an RT, write a test, dive into the PIR ...
