These validate values by their numerical properties.

Provides: "IsNumber", "IsInt"

Provides: "IsRefType", "IsScalarRef", "IsArrayRef", "IsHashRef", "IsCodeRef", "IsRegex"

These constraints deal with array references and their contents.

Provides: "HasArraySize", OnArrayElements, OnEvenElements, OnOddElements

All constraints appliable to hash references as well as their keys and values.
