You would think so, but apparently not. I found this example on page 482 of

Logically you would think that you would have to escape the "]" but you
don't seem to have it as strage as that seems.
because once you've escaped the [, it's no longer a matched pair of
capturing braces
You probably should still escape it for "correctness" but it's not
necessary. Since there's no "I'm inside a []" flag set, it's assumed
that it's just a normal ].
