std.typelist

[Jonathan M Davis]

As was recently pointed out on the Phobos list ( 
http://forum.dlang.org/post/CAEnAdhZTcuOL50TeRwCCG=E99nCA_Gh=y=TtHeUGKNuEaC072Q@mail.gmail.com 
), we technically have std.typelist (which I'd never heard of before that 
post), which Bartosz Milewski put together a few years ago. However, it's 
undocumented and not actually included in the build at all. The question is 
what to do with it.

It probably needs a bit of cleanup (e.g. making sure it follows the proper 
naming coventions everywhere), but honestly, I think that it looks pretty 
cool, and it probably wouldn't take much work to make it properly releasable.

Do we want to have someone look it over, take it over, and submit it for 
review? Or do we want to simply give it a look over and fully add it after a 
few tweaks? Or do we want to just toss it altogether? What do we want to do 
with it? We really shouldn't be leaving it sitting there like it is. As it 
stands, it's just forgotten cruft, which is a shame, since it does look pretty 
cool.
