A small shim over the proc_macro crate intended to multiplex the current
stable interface (as of 2017-05-19) and the upcoming richer
interface.
The upcoming support has features like:
- Span information on tokens
- No need to go in/out through strings
- Structured input/output
My hope is that libraries ported to proc_macro2 will be trivial to port to the
real proc_macro crate once the support on nightly is stabilize.
This crate is still very much a work in progress
