No I can't, since my code must work on older compilers, and I have = no
time to spend on pointless
changes that add nothing to the code.
Adding new features will break compatibility. If you = declare your code needs the -std=3Dc++20 flag then this kind of issue will = happen.

I'm sure you've done it for gcc, clang and msvc already, not to
mention every non-compiler tool
that parses C++. Where are your patches? Never mind, don't tell me,= I
don't want them.
I wrote some compiler extension in clang. So I think = it won't really be a huge change in the parse. And I don't think th= at my task is to patch every compiler.
