I wonder if the person who wrote the spec for RegExp is on this list. I
would like to ask one question: Was there any reason why the following
steps were defined in the present order:
The production Alternative :: Alternative Term evaluates as follows:
1. Evaluate Alternative to obtain a Matcher m1.
2. Evaluate Term to obtain a Matcher m2.
The production Alternative :: Term Alternative evaluates as follows:
1. Evaluate Term to obtain a Matcher m1.
2. Evaluate Alternative to obtain a Matcher m2.
or, was it a matter of preference? If any side effect I am missing
exists in the latter order, I need to reconsider or abandon my compact
