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.
