Re^7: Distinguish between missing and undefined arguments with subroutine signatures (semipredicate problem)

hmm ... you are going to extremes now. :)

->mutate(FIELD) is a getter for FIELD

->mutate(FIELD,VALUE) is a setter for FIELD

->mutate(FILED,VALUE,OTHER...) shouldn't compile

I think, in this particular case you can still apply a prototype of ($;$) together with the signature ($field,@values)

At least theoretically, not sure if it's still implemented that way.

well not with methods, see other post:
