The latest draft uses 'dt' to mangle member expressions, and now so do we.

-/// The standard ABI does not describe how member expressions should
-/// be mangled, so this is very unstandardized. We mangle as if it

-/// The standard ABI also does not assign a mangling to the dot
-/// operator, so we arbitrarily select 'me'.
