[PATCH] D99561: Support visitor pattern by PointerUnion.

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added a comment.

Right, if we look at our containers, we also find APIs that don't match exactly the standard (`DenseMap::find_as` or `insert_as` for example, or `SmallVector::pop_back_val`), so yes someone swapping `std::vector` for `SmallVector` may be surprised.
