Thanks for the initiative.

One comment:

+@item @var{keyword}
+@itemx @var{number}
+@itemx @var{string}
+Matches if the value is @code{equal} to the literal.
+This is a special case of @code{'@var{val}}, above,
+possible because these types are self-quoting.

Not all numbers are allowed; only integers - for example

(pcase .9
  (.9 t))

|-- Unknown pattern `0.9'

See the definition of `pcase--self-quoting-p', it's intentional.
