[PATCH] D137205: [clang-tidy] Add performance-unnecessary-copy-on-last-use check

[Fabian Keßler via Phabricator via cfe-commits]

Febbe added a comment.

I have a problem with lambdas capturing by copy implicitly (`[=]()...`). It seems like, that child nodes are not reachable via a MatchFinder unless they are spelled in source. I actually don't know how to prevent a fix elegantly: My proposed idea is, to check the source location of the capture list for each lambda and check, if the declRefExpr is part of it... . This is bug prone, and possibly slow.
