What's going on with std.experimental.lexer?

[Brian Schott via Digitalmars-d]

I've been looking at ways to optimize the D lexer's operation 
using SIMD instructions. I'm not yet sure if I'll need to change 
the lexer generator's API to do this. I'm going to wait until I 
have my proof-of-concept code and some benchmark results before 
asking for a voting thread or creating a pull request.
