I meant that there is a fundamental difference between a mere library alias and a library defined through a hypothetical "extend" library declaration:(define-library (srfi 158) (extend (srfi 121)) (export make-accumulator ...) (import (scheme base) ...) (begin ...))
Oh yeah, it's true that an `extend` that can be combined with other declarations has different semantics.
Already implemented in Unsyntax. :) Basically just two lines of non-trivial code.
Nice, fast work!
