Hmm... I think we should distinguish the "get element" of sequences and
the "get element" of tables.  The upcoming seq.el provides operations on
sequences, such as seq-elt and that doesn't apply to hash-tables because
I don't think we should treat them as sequences.

So, yes, support for hash-tables would fall into the `get' extension, or
whatever name we end up choosing.  I think we should probably come up
with a library akin to seq.el but for mappings (also known as
"functions" in set-theory).  It could be called map.el, maybe, and the
operation could be map-elt?
