compiler bugs, will they ever stop harassing me?

aka another reason to never use built-in arithmetic types.

#cpp

@namark Are you sure it is a compiler bug? I am not sure whenever it actually is one or not tbf

@Archivist are you a gcc alt? stop gaslighting meeee >.<

otherwise, please elaborate, good sir, what is your objection? o.O

@namark nah, I am just accustomed at how confusing the standard is

@Archivist don't make me read the standard, I'll defect report :<

@namark

The basis for my questioning here is that primitive operators in C++ are not functions, so whenever they warrant implicit conversions or not with a behaviour similar to an actual function is questionable

I will actually investigate that a bit and tell you my findings

@namark

I confirm that this is a bug of GCC linked to templates. You can circumvent that bug using concepts in a portable fashions (see here: https://godbolt.org/z/PzT9eeTj4)

@Archivist concepts are nice... the ranges and modules baggage though... also not going to use a standard that's barely not even done implemented yet so far.

The real workaround is

template<typename T, size_t D>
int operator+(int, One<T,D>);

and so on, and if that's all you needed maybe making the conversion explicit, not that gcc respects explicit
