Applies @racket[transformer] as a @tech[#:doc refman]{syntax transformer} to @racket[stx] in the
current expansion context. The result is similar to expanding @racket[(m stx)] with

guaranteed to stop after applying a single macro transformation (assuming @racket[transformer] does
not explicitly force further recursive expansion).

Unlike simply applying @racket[transformer] to @racket[stx] directly, using
