Of course that includes static member functions, where the 'this' 
pointer is removed.

Actually, "static opCall" is kind of different because it makes the type 
itself callable.

Another use of 'static' that means "at compile time":

static assert

4. Module initialization and deinitialization:

static this
shared static this

static ~this
shared static ~this

5. Module import:

static import std.stdio;
