Array toHash()

I have a class which contains an int[] and some other stuff. I want to
use my class as the key for an AA, so I am overriding toHash(). But the
int[] is the only part which should produce the hash code. I know that
int[].toHash() is defined somehow, because I can put int[] directly into
an AA without writing any hash functions. But I don't know how to spell
this explicitly or force the compiler to generate it for me so that I
can forward to it in my toHash(). For illustration:
class Foo
{
override
size_t toHash() @trusted pure const nothrow
{
// error: no property 'toHash' for type 'int[]'
return importantStuff.toHash();
}
// override opEquals() too...
int[] importantStuff;
bool notImportant;
int ignoreMe;
}
Any way to avoid re-implementing this hash function?
