I'd be in favour of H' supporting "typealias" as well as "type". This
would lead the way, via compilers giving warning for uses of "type", to
dropping support for "type" more painlessly in a future standard. Too
much code has variables called "typ"...

I think the same with "data" and "datatype" would be nice too. I also
have a number of variables called "dat" dotted around.

We could still use "type" in export lists, if desired, in the same way
we use can still use things like "export" in FFI exports (i.e. you might
have to export "variable type" rather than an unqualified "type").
