----------------
I think, we should use a node matcher for `UnresolvedLookupExpr` and instead use `callExpr(callee(unresolvedLookupExpr().bind("something")))`.

Also, I would create the new matcher in the ASTMatchers.h right away, together with a test and docs. But if you want this patch to be in soon, feel free to move the matcher to the matchers library in a follow up.
