Other associative array to compare the internal one with.
true if the internal associative arrays are equal; false if not.
MutexedAA!(string[int]) aa1; aa1.setup(); // important! aa1[1] = "one"; aa1[2] = "two"; string[int] aa2; aa2[1] = "one"; assert(aa1 != aa2); aa2[2] = "two"; assert(aa1 == aa2);
Implements opEquals for this type, comparing the internal associative array with a different one.
