By splice expand I mean that there is a match front end that can handle patterns of this form: (match ... ,@(foo)) Where foo is syntax-local-value looked up as a macro, and then called on the syntax (directly, as a function without local expand). The result is deconstructed as #'(pat ...) and spliced into the expansion for the normal (scheme/match) match. So there is no local expand, but the type like expansions are contained in such a foo, which came from a macro which itself introduced a rename. [yikes, I know] -- vyzo
