I think that Allocator shouldn't be defaulted because it's deduced from the argument. Otherwise looks good.

Good point, isn't that true for all of basic_memory_buffer's template arguments here?

Never mind, the defaults means I can pass {} and get the defaulted values. I think that means I can remove the default SIZE then.

It's true for SIZE (could you remove the default while at it?) but not for Char which is used for SFINAE.

Oh, but it must be an lvalue. Sorry for the stream of thought here.

I pushed another version that removes the default template argument for vformat_to. Let me know if you want me to limit the change to just format_to.

Please limit the changes to format_to.

How do you see the default argument to Char being used?
I guess something like:
format_to<std::basic_string<wchar_t>>(...)There was a problem hiding this comment.
But it's still deduced from buf, right? 🤔

Updated to limit the change to format_to.

Does clang-format still break this onto the next line?

Oops, thanks, this time run through clang-format.
…rmat_to Remove deduced default template arguments in format_to and moves the SFINAE check to a non-deduced template parameter.
