--- Comment #3 from Dlang Bot <dlang-bot@dlang.rocks> --- @aG0aep6G created dlang/phobos pull request #7147 "prepare for fix of issue 20138 ("is expression not evaluating correct…" mentioning this issue: - prepare for fix of issue 20138 ("is expression not evaluating correctly?") With issue 20138 fixed, `const U` and `shared U` do match `const shared T`, and they leave the other qualifier intact. So `const shared U` must be attempted first if we want to strip both qualifiers. https://github.com/dlang/phobos/pull/7147 --
