--- Comment #3 from Blatnik <[email protected]> --- Here's a "fixed" version of core.internal.array.equality.__equals that acts correctly in betterC. I'm sure it could be done better but at least it works. bool __equals(T1, T2)(scope T1[] lhs, scope T2[] rhs) if (!__traits(isScalar, T1) || !__traits(isScalar, T2)) { if (lhs.length != rhs.length) return false; if (lhs.length == 0) return true; static if (useMemcmp!(T1, T2)) { if (!__ctfe) { static bool trustedMemcmp(scope T1[] lhs, scope T2[] rhs) @trusted @nogc nothrow pure { pragma(inline, true); import core.stdc.string : memcmp; return memcmp(cast(void*) lhs.ptr, cast(void*) rhs.ptr, lhs.length * T1.sizeof) == 0; } return trustedMemcmp(lhs, rhs); } } foreach (const i; 0 .. lhs.length) { static if (__traits(isStaticArray, at(lhs, 0))) // "Fix" for -betterC { if (at(lhs, i)[] != at(rhs, i)[]) // T1[N] != T2[N] doesn't compile with -betterC. return false; } else { if (at(lhs, i) != at(rhs, i)) return false; } } return true; } --
