Publish the
stdlib.Functions()directly to enable extension of most of the standard library.Operators such as
+,-,==, etc. do not support extension as they are marked as singletonimplementations; however, most human-readable overloads such as
containssupport extension.Rather than split the stdlib into an
cel.EnvOptionfor a set of declarations and acel.ProgramOptionfor a set of function implementations, the library has been published as a set of
decls.FunctionDeclinstances which support merging an dynamic dispatch with type-safety.
