- While porting a big C-Prolog program to SICStus Prolog, I encounter
- the following problem:

- To make the program readable, I gave a name to many variables which
- are essentially _ (don't care). When (re)consulting my program,
- every time many screens of such warnings are produced which
- slow down the testing and programming annoyingly.
- [...]
-
- A variable is considered "don't care" if it is *prefixed* with _. i.e.
- if you want the variable ListOfTerms to be a don't-care variable for
- which you don't want a singleton-variable-warning, you can write it as
- _ListOfTerms.
