LGTM, thanks for the RFC! What about visibility? I suppose this works even outside the object scope? should this be mentionned? $foo = $this->somePrivateMethod(1, ?) Would it make sense to support a way to use a placeholder for "all remaining args"? Eg: $foo = some_func(1, ...?) Combined with my previous comment, this could replace Closure::fromCallable() by a language construct, which is something that we already discussed in another thread (we talked about some ::function special suffix instead): $foo = $this->somePrivateMethod(...?) In this last form, we might make this result in Closure::fromCallable() exactly. Aka no increase of the depth of the stack trace. BTW, ideally, partial functions should not increase the depth of the stacktrace at all. Do they? Nicolas
