Test case:
------------------------
class TestClass
{
int a;
this()
{
enum c = getAttribute!(TestClass.a);
}
}
int getAttribute(alias target)()
{
return 0;
}
------------------------
produces this error in DMD 2.063:
Error: value of 'this' is not known at compile time
This is annoying as you can use e.g. __traits(getAttributes, TestClass.a) but
you can not wrap this call into a template because of this bug.
A workaround as mentioned by Andrej Mitrovic is adding static to the
getAttribute template declaration.
