Possible regression of the @_functionBuilder type-checker between Xcode 11.1 and Xcode 11.3.1

      Description

      See the attached playground: this (fairly straightforward) function builder builds & functions fine with Xcode 11.1's toolchain, but fails to build as of Xcode 11.3.1.

      As far as I can tell there is nothing wrong with the code – simply `.collect` method at line 43 throws the compiler into a ditch.
