You should document an alternative à-la Perl form of conditional execution, using the special
"or" and "and" construct:
Here is the equivalence for the "or" special syntax construct:
expression1 or statement;
if (!(expression1)) statement;
Here is the equivalence for the "and" special syntax construct:
expression1 and statement;
if (expression1) statement;
These constructs can be combined in complex logic expressions, with "and" having a higher
priority that "or":
expr1 and expr2 or
expr3 and expr4 or
statement
is equivalent to:
if (!( (expr1) && (expr2) ||
(expr3) && (expr4) ))
statement;
