We need a vocabulary to name things precisely.  In the thesis, I have
used the
term "production" to indicate a term of the form:
  prod = ... | ... | ...;
and I used the term "alternative" to name each [...] component in the
above term.

So, strictly speaking, {Factor} is NOT an alternative; it is the "name"
of the alternative "{Factor} Factor".

The alternative name is used in conjunction with the production name to
create the name of the related AST node type: AFactorExpr.

I have contributed the front-end, as well as the points-to analysis:-) 
Any volunteer to contribute a back-end?
