[vinniefalco]

if there is already full coverage then we can close this?

[vinniefalco]

This seems kind of harsh... throwing? Anyway if we are going to throw we need to use the helpers in detail/except.hpp.

[MungoG]

Throwing is consistent with the behaviour of both fmtlib and std::format. Code that works with this implementation therefore has a clear migration path in the future.
Will change to use the helpers.

lets make sure we squash this down and have correct grammar in the commit message please
