Need to create ArgList iteratively

[abrownsword]

I haven't found an obvious way to do this (even in 5.1). I have an array of objects that I need to pass as arguments to fmt::vformat, but they require a bit of conversion to extract the native types understood by fmt. I think what I want to do is create a format_arg_store, but add to it incrementally rather than via a single variadic call. Is there an existing mechanism to do this? If not, could one be added? I can specify the arg count up front.

This has already been discussed in #814 and addressed in #819.

Thanks -- wasn't sure what to look for in terms of existing issues, and I've only downloaded the last release not pulled from HEAD.
