In modern C++, a 'bool' can have exactly two values: 'true' and 'false'.
When promoted to an integer type, 'true' translates to '1' and 'false'
translates to '0'.  When converting from an integer type to 'bool', '0'
becomes 'false' and everything else becomes 'true'.  In other words,
'int(bool(5))' evaluates to '1'.  The comparison operators (==, !=, <, etc.)
all yield a value of type 'bool'.
