Compile error using variadic templates multiple times as arguments with VS 2019.27

Basic information

• source code is below this text.
• compiles with nearly every compiler not older than 5 years (gcc 6, ...)
• compiles NOT with MS VC up to MS VC 2019 16.27
• looks like there's a problem using a variadic template as a argument prototype of a function pointer more than once.

Questions:

• code wrong or compiler wrong??
• any possibility to write this more elegant and more standard conform so MS VS compiles it?
• output at the end of the code is from compiler explorer.
