Package rangefunc rewrites range-over-func to code that doesn't use range-over-funcs.
Rewriting the construct in the front end, before noder, means the functions generated during
the rewrite are available in a noder-generated representation for inlining by the back end.

	// . elements as well as trailing or duplicate separators. For
