There was a problem hiding this comment.
Shouldn't the compiler be able to infer the scope const here?

This one of several PRs I intend to submit, breaking up #2677 into multiple PRs.
Background
This PR is in support of dlang/dmd#10382
inas a parameter storage class is defined asscope const. Howeverinhas not yetbeen properly implemented so its current implementation is equivalent to
