The type restrictions on the recurrent cell input only existed to match the input and weight types. Now, we have
_match_eltype
, so we don't need such strong restrictions. This simplifies the type signature so that weird types likeNil
can also pass through (and_match_eltype
already support handling these).A nice benefit is that we don't need to have a special
outputsize
rule for recurrent cells anymore.PR Checklist
