case classPFAVersion(major: Int, minor: Int, release: Int) extends Ordered[PFAVersion] with Product with Serializable
Describes a PFA (the language) version number as a triple of major number, minor number, release number (all non-negative integers).
The version has a strict ordering (numerical lexicographic).
Used to specify a version in which to interpret a PFA document and to label the beginning and end of support of function signatures.
It could, in the future, be used to label support ranges of special forms, too, but that would always be managed by hand within the special form's constructors.
