Why not?
It makes no sense to have a record type `hash-table` because that type
is already used for something else, so there's no ambiguity for
`#s(hash-table`
Basically, the general syntax is `#s(<type> <foo>)` where <foo> is
interpreted depending on <type>.

I don't think it attempts to really be compatible with this, but yes,
it was inspired by it.
