As I understand it, there are three keywords: VOLATILE, STRICT, and
IMMUTABLE. Putting one of those keywords into the declaration flags
the function accordingly; if none is given, VOLATILE is assumed.
Declaring the function as "STRICT IMMUTABLE" or "STRICT VOLATILE"
seems at best redundant (the word "STRICT" is mere noise), and at
worst confusing (the parser might be interpreting it as "STRICT", not
as the other keyword). Or is there something I'm missing here?
