Hello.

i need to enumerate all module variables of the given types (it's easy, this is not the question) and make list of only __gshared ones. of course, i'm talking about CTFE.

is there any hack/trick to determine if variable is __gshared? or if it is a thread-local, for that matter?

i added 'isGShared' trait to my compiler, but i'm not expecting from others to do the same. ;-)

the only hack i invented is this abomination:

  int v0;
  __gshared int v1;


  enum isGShared(alias var) =
    !__traits(compiles,
      mixin("{auto a___ = function typeof("~var.stringof~
            ") () @safe { return "~var.stringof~"; };}"));


  pragma(msg, isGShared!v0); // false
  pragma(msg, isGShared!v1); // true


sure, it's very limited, and we must do alot of checks before using it. it *SEEMS* to work, but i not tested it very well.

There is the -vtls compiler switch.

let me quote myself: "i'm talking about CTFE". i need to build mixin string with this variables, to be precise.
