`syntax-local-introduce` is no longer useful for this purpose since the switch to the scope sets model. Other scopes, such as module scopes, will often distinguish the macro-introduced name. For example, using `syntax-local-introduce` won't produce the desired behavior when `req2` is defined in one module and used in another.
