> Also, expanding directly to std::format would limit this to cases where only the appropriate std::string variant can be used. While it may seem inconvenient, being able to do something like this:

I was only showing examples using F"", and std::format, because I think it's easier to see how they expand/interpolate, since there are parentheses and such.


For purely string-interpolation, one would use X"", which extracts the expressions into their separate arguments.

So you could use it like this:

std::print(X"Values of {gamma} may give rise to {condition}");

FormatQString(X"Values of {gamma} may give rise to {condition}");


Which would become these:

std::print("Values of {} may give rise to {}", gamma, condition);

FormatQString("Values of {} may give rise to {}", gamma, condition);
