Description
Currently the quantity of proof in with-clause is the same as the quantity of expression. But often proofs are needed only at compile time. Example:
So I suggest adding the ability to separately specify quantities for proofs.
Note that
prf
is currently erased in the following code, but in this version it will now be unrestricted, as will all variables for which multiplicity is not explicitly specified. This may affect existing code and probably requires discussion.Should this change go in the CHANGELOG?
implementation, I have updated
CHANGELOG_NEXT.md
(and potentially alsoCONTRIBUTORS.md
).
