Maybe, like the "enum" extra parameter (as proposed in a patch that appears
to not be merged yet), there should be a "bool" one, indicating for some
languages that it should map to their built-in bool type. Like the
enumerations, it can still be an int or uint in the C api so it won't
change anything other than add some documentation and type safety to other

Or the enum proposal could be enhanced by special-casing the enum named
"bool", if this is considered a simpler change to the syntax.

Note that just making it an actual enum with "true" and "false" keys won't
work for language wrappers, due to a certain language named after a snake
that uses "True" and "False" (ie capitalized)...
