  * difficulty:  => Unknown


Comment:

 Yes I see that.  What would you like? Should `mkName` fail (by calling
 `error`) when given an illegal name?

 I wonder if some people might use an illegal name specificaly to ''avoid''
 the danger of accidental capture?  (Though you can always use `newName`
 for that.)

 Perhaps it would suffice to reject spaces in names, becuase that is
 perhaps particularly confusing.

 Simon
