+// A simple type system for compiler-internal use. It is based entirely on
+// union types, and all subtyping hence amounts to set inclusion. Besides
the
+// obvious primitive types and some predefined unions, the type language
also
+// can express class types (a.k.a. specific maps) and singleton types
(i.e.,
+// concrete constants).
+//
+// The following equations and inequations hold:
+//
+// None <= T
+// T <= Any
+//
+// Oddball = Boolean \/ Null \/ Undefined
+// Number = Smi \/ Double
+// Name = String \/ Symbol
+// UniqueName = InternalizedString \/ Symbol
+// InternalizedString < String
+//
+// Receiver = Object \/ Proxy
+// Array < Object
+// Function < Object
+//
+// Class(map) < T iff instance_type(map) < T
+// Constant(x) < T iff instance_type(map(x)) < T
+//
+// Note that Constant(x) < Class(map(x)) does _not_ hold, since x's map can
+// change! (Its instance type cannot, however.)
+// TODO(rossberg): the latter is not currently true for proxies, because
of fix,
+// but will hold once we implement direct proxies.
+//
+// There are two main functions for testing types:
+//
+// T1->Is(T2) -- tests whether T1 is included in T2 (i.e., T1 <= T2)
+// T1->Maybe(T2) -- tests whether T1 and T2 overlap (i.e., T1 /\ T2 =/=
0)
+//
+// Typically, the latter should be used to check whether a specific case
needs
+// handling (e.g., via T->Maybe(Number)).
+//
+// There is no functionality to discover whether a type is a leaf in the
+// lattice. That is intentional. It should always be possible to refine the
+// lattice (e.g., splitting up number types further) without invalidating
any
+// existing assumptions or tests.
+//
+// Internally, all 'primitive' types, and their unions, are represented as
+// bitsets via smis. Class and Constant are heap pointers to the respective
+// argument. Only unions containing Class'es or Constant's require
allocation.
+//
+// The type representation is heap-allocated, so cannot (currently) be
used in
+// a parallel compilation context.
