I'm sure that it is possible to design around that.
The limit simply simplified a lot of things. I couldn't see any
serious problem with it. I'll "pay" for it in the implementation of
vectors, but then again, I'll get sub-object greying in exchange for
I also generally like the idea of using tries for large arrays in lisp
dialects -- in exchange for minor complexity in some primitive
operations I get back good (and nearly automatic) support for sparse
arrays and similar tricks. In a vague way, this seems like the same
sort of benefit one gets from having bignum support.
