I'd welcome a webassembly package into GNU ELPA, indeed.

Not sure exactly what you mean here.  What have you tried that didn't work?

For the parsing needed for indentation and such, I think syntax-tables
should work just fine (with maybe a bit of syntax-propertize for (;...;)
comments).

As for real parsing for subsequent processing such as interpretation,
I'd try to just use `read` with some pre/post processing to handle the
few incompatibilities.
