 And some caveats:
 
-1. For _any_ error-correcting code, attempting to _correct_ errors

    In the HD=4 example, we assumed 1 bit-error. If we were wrong and
    there were actually 3 bit-errors, we would have "corrected" to the
    wrong codeword.
 
-   In practice this isn't _that_ big of a problem. 1 bit-errors are
-   usually much more common than 3 bit-errors, and at 4 bit-errors you're
-   going to have a collision anyways.

    Still, it's good to be aware of this tradeoff.
