Deprecation message from phobos compiling a vibe.d app.

Jan 30, 2020

When building my small vibe.d app I am getting this messages twice: /usr/include/dmd/phobos/std/range/primitives.d(174,38): Deprecation: alias byKeyValue this is deprecated - Iterate over .byKeyValue instead. /usr/include/dmd/phobos/std/range/primitives.d(176,27): Deprecation: alias byKeyValue this is deprecated - Iterate over .byKeyValue instead. /usr/include/dmd/phobos/std/range/primitives.d(174,38): Deprecation: alias byKeyValue this is deprecated - Iterate over .byKeyValue instead. /usr/include/dmd/phobos/std/range/primitives.d(176,27): Deprecation: alias byKeyValue this is deprecated - Iterate over .byKeyValue instead. Unfortunately I don't know what is triggering this and what to do about. The build is working, so it is more a question of elegance.

That's probably triggered by some constraints. I had the issue like this with Nullable: https://github.com/dlang/phobos/pull/7324

I had the issue like this with Nullable: https://github.com/dlang/phobos/pull/7324 The core problem here stems from the fact that templates are always instantiated in the scope of the template declaration [1]. Hence dmd instantiates some template using a deprecated symbol in a non-deprecated scope and issues these warnings. I'm currently working on a PR [2] to resolve this issue but still have to fix some issues when dealing with overloaded symbols as template alias parameters.
