Advise for syntax highlighting

[Jacob Carlborg via Digitalmars-d]

I'm currently updating the TextMate D bundle for D2. I have a couple of 
questions for how to highlighting some specific code or how other 
editors/IDE's highlight them.

* "this" in constructor

this () {}

In TextMate functions/methods are highlighted, should this be 
highlighted as a keyword or as a method?

* "this" in copy constructor

this (this) {}

The "this" parameter, should that be highlighted as a keyword or as a 
parameter?

* The "__ctfe" variable

if (__ctfe) {}

How should this highlighted? I see a couple of alternatives:

- not at all
- as a keyword
- as a special recognized built-in symbol, similar to __LINE__
- as a special recognized library symbol. For example, in the C bundle 
many of functions in the standard library are specially recognized and 
highlighted differently. This might not apply here since it's not a 
library symbol

* __traits identifiers

__traits(allMembers, Foo);

In this case "allMembers". Basically the same question and alternatives 
as for the "__ctfe" variable.

* Predefined version identifiers

version (OSX) {}

Again, same a question and alternatives as for the "__ctfe" variable.

* Extern identifiers

extern (C)

Again, same a question and alternatives as for the "__ctfe" variable.
