HexStrings:

    http://dlang.org/lex.html#HexString

They're rarely used, but very useful when needed. But, as the octal literals have shown, they can be easily replaced with a library template:

    x"00 FBCD 32FD 0A"

becomes:

    hex!"00 FBCD 32FD 0A"

It'll simplify the core language slightly.

Thoughts? Anyone want to write the hex template? Any other ideas on things that can removed from the core language and replaced with library entities?

The motivation for this came from a post by deadalnix.

And I'm obviously all for it :)

Wrong link? Or wrong thread?

Can we make it so it returns a ubyte[]?

I'd be interested. Here's a quick draft based on octal:

There is an enhancement request on this (for the built in hex strings).

I think you've got the right idea. Time for a pull request?

P.S. Also need to include all the examples in the dlang reference as unittest cases.

Unfortunately, it needs to be a dropin replacement for x"...", which returns a string/wstring/dstring.
