Yes but in a C extension. The code I have is not working with 1.9.

Well not exactly. sort_by works but I'd prefer to use sort! with a
block, as it does the sorting in-place.

In 1.9, if I inspect "ary" below, I only see the current array element.
In 1.8, it is an array of the two elements which are being compared.

static VALUE
sort_i(VALUE ary)
{
long v1 = FIX2LONG(RARRAY_PTR(ary)[0]);
long v2 = FIX2LONG(RARRAY_PTR(ary)[1]);
return LONG2FIX(v1 - v2);
}
