Why not
lower array and AA literals to expression tuples (or
whatever) to
make the convenient syntax usable with custom (possibly
non-GC safe)
containers as well? A GC'd default implementation could then

provided in druntime, just like today's arrays and AAs.

AA's are moving into druntime. Yours truly is supposed to make

This moves the _implementation_ to druntime, but there is still
realistically no way to use AA literals with my own non-GC'd
version of hash maps without shipping a custom druntime (and thus
modifying the semantics of an existing language construct). What
I'm talking about would let you do things like
MyVector!int stuff = [1, 2, 3, 4, 5];
without needing a (temporary) GC'd allocation, and thus please
the GC-hater crowd because they can still have all the syntax
candy with their own containers, even if they can't resp. don't
want to use the default GC'd constructs.
