I can check againts if member is either static function or 
template. But I failed to check if it both static and 
templated.


The best I could come up with is:

struct Foo
{
static staticMethod()
{
}

static templatedStaticMethod(T)(T t)
{
}
}

void main()
{
static if(__traits(isTemplate, Foo.templatedStaticMethod) &&
  __traits(isStaticFunction, 
Foo.templatedStaticMethod!int))

{
 writeln("win");
}
}

It seems like a templated method can be queried if it is static 
only after it's instantiation. Hope this helps.

I would kinda argue that it's a bug, because checking whether a 
template function is static can become very complex if the 
template also has constraints etc.
