Is nightly still required?

[thedodd]

After reviewing #8 (about 5 months old), looks like this crate was cut over to proc-macro system. As proc-macro has recently stabilized, I figured I would ask.

Sadly, it's still required. Features this library seems to need (gotten by deleting the #![feature] block from lib.rs and compiling on stable) are as follows:

• proc_macro_span
• rustc_private

Although the rustc_private features could probably be replaced with unicode_xid

[palfrey]

So, this got mostly fixed by #19 but the README still refers to nightly being needed.

@palfrey, thanks for pointing that out. I've removed the nightly note!
