quote_precise

A version of quote that preserves Span locations

//junk Spans
let t: Token![!] = parse_quote! { ! };
println!("{:?}:{:?}-{:?}", t.span, t.span.start(), t.span.end());

//useful Spans
let t: Token![!] = parse_quote_precise! { ! };
println!("{:?}:{:?}-{:?}", t.span, t.span.start(), t.span.end());
assert_ne!(
   t.span.start(),
   t.span.end()
)

Waiting on proc_macro::Span to stabilize a bit more to see if further work on this crate is not entirely redundant effort.
