Description
We have a
FunExt
interface containing general enough proposition, for omega-quantitied functions. But this property is also useful for functions taking arguments with the other quantities as well. Thankfully, these properties are derivable from the existing one, so I propose to add them with their proofs to the library.Should this change go in the CHANGELOG?
implementation, I have updated
CHANGELOG_NEXT.md
(and potentially alsoCONTRIBUTORS.md
).
