Am using Textadept, the highlighting is as follows:

highlighted as keyword:
this()
__traits
extern(C) // The "extern"; "C" isn't highlighted at all

highlighted as a special recognized built-in symbol, similar to 
__LINE__:
version(OSX)  // the OSX; "version" is highlighted as keyword

not highlighted at all:
__ctfe
