I have not expressed myself well enough, I am sorry. This bug report is a
"diagnostic" one, it's not a "rejects valid". So I agree that this code needs
to be refused at compile time, but is this a good message?
test.d(4): Error: pure function 'foo' cannot call impure function 'putchar'
foo() doesn't contain putchar(), it's bar() that calls it.
I don't know what is a good error message for this situation.
This is a reduced test case:
void foo() {}
pure void bar() {
void spam() {
foo();
}
}
void main() {}
Maybe you are right, there is no much better error message to be invented here.
