The table could have weak keys, and there are known GC algorithms for dealing
with those.
It doesn't actually need to be a hash table at all -- we only need to optimise
for fast insertion and small size, not lookup (for displaying compiler
diagnostics, for example).
This is a very half-baked idea; I haven't thought it through at all. For
example, we may need a way to transfer location from one sexp to a newly built
one, and that may complicate the inner workings of the compiler (or not).
It's clear that symbols-with-pos is a neat hack that is surprisingly effective,
with almost no changes to Lisp code needed at all. It definitely has improved
diagnostics. Unfortunately it makes everything a bit slower, not just the
compiler, but symbols-with-pos will serve until we come up with something
better.
