The equality test is necessary if it was given originally (meaning, if
it's not 'eql).  I don't think we should ever omit it, even if it's the
default value, for readability.

The :weakness, :rehash-size, and :rehash-threshold options to
make-hash-table, can probably be omitted when they are the defaults.

Would this work?

#s(hash-table size 2 test equal data (k1 v1) (k2 v2))

Finally, the size is just a hint with make-hash-table; should the (read)
allow wrong sizes or throw an error?

Thanks
