This sample code comes from bug 4269 (it's already closed):

Code:
----
static if (__traits(compiles, A.sizeof))
{
    pragma(msg, "A.sizeof compiles!");
}
class A
{
    void foo(B b);  // line 7
}

Output:
----
test.d(7): Error: undefined identifier B, did you mean class A?
A.sizeof compiles!

Why pragma declaration inside "static if" is evaluated?
