Try to run:
dmd test.d
It says:
/usr/include/dmd/druntime/import/core/sys/posix/sys/types.d(100): Error:
undefined identifier 'c_long'
It looks normal but it's not documented. It's just that the
import is not yet known in the scope.
To be clearer, the problem is the same with:
void main()
{
foo;
void foo(){}
}
Exactly the same thing happens. There's already 3 semantic
passes. To solve this kind of forward references another semantic
pass would be required. But in this case you couldn't determine
how many passes would be necessary so there would be a
complexity problem in the compiler.
