-- A t'GI.GObject.Objects.ParamSpec.ParamSpec' derived structure that contains the meta data for t'GVariant' properties.
-- 
-- When comparing values with 'GI.GObject.Functions.paramValuesCmp', scalar values with the same
-- type will be compared with 'GI.GLib.Structs.Variant.variantCompare'. Other non-'P.Nothing' variants will
-- be checked for equality with 'GI.GLib.Structs.Variant.variantEqual', and their sort order is
-- otherwise undefined. 'P.Nothing' is ordered before non-'P.Nothing' variants. Two 'P.Nothing'
-- values compare equal.
