I belive it indexes with a single char into an array right now, but
that is just a matter of string parsing, {...} is not hard to do.

Bear in mind that using extensions force you to disable the GCC
format checks, a heavy cost to bear.

Also bear in mind that any work on this should keep an eye on, and if
at all possible collaborate with GLIBC for maximum compatibility.

Never attribute to malice what can adequately be explained by incompetence.
