While the test case for #7826 now works, for some reason I'm still getting
the same warning in my own projects (but without "pure" being included in
"must be declared as...") even though they which use the *exact* same
toHash function (well, except "str" having a different name). I'll try to
figure out a new test case after I get some sleep...
/facepalm: With Beta2, I wasn't getting the probelem with the original test
case (ie "const hash_t toHash()") because I wasn't compiling it with
warnings enabled.
So here's the "issue" now, *if* it even is an issue (I'm not sure):
With Beta2's current fix for #7826, I can do this without warnings or
errors:
struct Foo {
string str;
const nothrow @safe hash_t toHash() {
return typeid(string).getHash(&str);
}
}
But, this (ie, removing nothrow and/or @safe):
struct Foo {
string str;
const hash_t toHash() {
return typeid(string).getHash(&str);
}
}
Gives me a warning:
Warning: toHash() must be declared as extern (D) uint toHash() const nothrow
@safe, not const uint()
Is this the correct behavior or not? Jonathan's comment over here (
http://d.puremagic.com/issues/show_bug.cgi?id=7826 ) suggested that toHash
in a struct shouldn't require nothrow or @safe. I'm refraining from having
any opinion on the matter ATM, I just wanted to bring it up in case the
current fix is incomplete.
