Adding `a` to `TypeNames` (e.g. `TypeNames: [a]`) or parenthesizing the type (i.e. `new (a *[])`) would solve the problem, so I'm not sure if we ought/need to fix it. If you really want to handle it, I'd suggest that you implement `UnwrappedLineParser::parseNew()` for C++ `new` expressions instead.
