It is valid code. It is "weak pure". "pure' keyword means both

Not gonna argue latter but former is just wrong.
struct Test
{
int a;
pure int foo1() // strong pure
{
return 42;
}
pure int foo2() // weak pure
{
return a++;
}
}
Signature is the same for both functions.
Think of all your member functions as non-member functions taking
the object as a ref parameter.
pure int foo1(ref Test this) {
return 42;
}
shouldn't be strongly pure (as it can access mutable non local
state).
