That should be "\1" and "\2" instead of $1 and $2. I should
have caught that before I sent off my email. :-S
Also note that $xTerm, $xNon_term, and $xArrow should only
use non-capturing parentheses, if at all. $xAlphabet should
preferably do the same, as a coding style, although it
doesn't impact this example.
