MergeMaps creates a new types map from union of specified type maps.

NewEmptyMap creates new type map that has no types in it.

NewMap returns new Map that is initialized with the provided types (separated by "|" symbol).

NewMapFromMap creates Map from provided map[string]struct{}.

WArrayOf means that expression is array of another expression E.g.

WBaseMethodParam is a way to inherit base type method type of nth parameter.

WClassConstFetch is a const fetch from a class.
