Comment (by hinder):

 I assumed that the built-in mathematical functions which Cactus supports
 in parameter file expressions, such as sqrt, would also be reserved words.
 It's possible that we have a different namespace for functions and
 constants, but I don't think that is a good idea.  I also think that
 parameter files should not allow the same parameter or constant to be
 defined more than once, and that the ordering of statements in a parameter
 file should not matter.  i.e. the above fragment should give an error
 about a multiply-defined constant.
