It sure looks that way to me. (But who am I to say?)

Protection, protection, ...  Seems the name of the game.

I don't understand any of it but, indeed, so it does.

Your

	\let\oldlangle\langle
	\def\langle{\protect\oldlangle}
	\let\oldrangle\rangle
	\def\rangle{\protect\oldrangle}

though, is ...  "ad angulum".

Well, if it does nothing to help me comprehend where that B came from (remember, every other mathematical symbol worked by itself), no question about it, you resolved my current difficulty!

Grateful, if puzzled, regards
