Named 'Constant' here for backwards compatibility.
This is similar as the primitives supported in the well-known type `google.protobuf.Value`, but richer so it can represent CEL's full range of primitives.
Lists and structs are not included as constants as these aggregate types may contain Expr[google.api.expr.v1alpha1.Expr] elements which require evaluation and are thus not constant.
Examples of literals include: `"hello"`, `b'bytes'`, `1u`, `4.2`, `-2`, `true`, `null`.

An overload indicates a function's parameter types and return type, and may optionally include a function body described in terms of Expr[google.api.expr.v1alpha1.Expr] values.
Functions overloads are declared in either a function or method call-style. For methods, the `params[0]` is the expected type of the target receiver.

An abstract representation of a common expression.
Expressions are abstractly represented as a collection of identifiers, select statements, function calls, literals, and comprehensions. All operators with the exception of the '.' operator are modelled as function calls. This makes it easy to represent new operators into the existing AST.
All references within expressions must resolve to a Decl[google.api.expr.v1alpha1.Decl] provided at type-check for an expression to be valid. A reference may either be a bare identifier `name` or a qualified identifier `google.api.name`. References may either refer to a value or a function declaration.
For example, the expression `google.api.name.startsWith('expr')` references the declaration `google.api.name` within a [Expr.Select][google.api.expr.v1alpha1.Expr.Select] expression, and the function declaration `startsWith`.

A comprehension expression applied to a list or map.
Comprehensions are not part of the core syntax, but enabled with macros. A macro matches a specific call signature within a parsed AST and replaces the call with an alternate AST block. Macro expansion happens at parse time.
The following macros are supported within CEL:
Aggregate type macros may be applied to all elements in a list or all keys in a map:
The `has(m.x)` macro tests whether the property `x` is present in struct `m`. The semantics of this macro depend on the type of `m`. For proto2 messages `has(m.x)` is defined as 'defined, but not set`. For proto3, the macro tests whether the property is set to its default. For map and struct types, the macro tests whether the property `x` is defined on `m`.
