forward referenced error in some cases (nested class)?
for these 2 files:
// testa.d:
module testa;
import testb;
class A {
B.C bc;
void test(/+B.C bc+/) {
B.C bc = null;//OK;
}
}
// testb.d:
module testb;
import testa;
class B {
class C {
void test(/+A a+/) {
}
}
}
try compile with dmd 1.0
dmd -c testb.d
or
dmd -c testb.d testa.d
testb.d(4): class testb.B is forward referenced when looking for 'C'
testb.d(4): class testb.B is forward referenced when looking for 'C'
testa.d(5): Error: no property 'C' for type 'testb.B'
testa.d(5): Error: B.C is used as a type
testa.d(5): variable testa.A.bc voids have no value
but with
dmd -c testa.d testb.d
no errors (and linked correctly later also).
btw, dmd seems to be sensitive for files order, (e.g when building the DWT lib, some cases, build ok, but linker errors when use the lib file, just by some diff order the files was supplied (e.g build 2.08, 2.09, 2.10, 3.04, the compilation order is diff))
Should these be considered bugs.
Not very sure, sorry.

//test.d:
class A {
B.C bc;
void test(/+B.C bc+/) {
B.C bc = null;//OK;
}
}
class B {
class C {
void test(/+A a+/) {
}
}
}
dmd -c test.d
errors.
//test.d:
class B {
class C {
void test(/+A a+/) {
}
}
}
class A {
B.C bc;
void test(/+B.C bc+/) {
B.C bc = null;//OK;
}
}
dmd -c test.d
OK.
