Missing reference documentation (Godoc)

[broady]

Here's a list of important functions and types that don't have documentation, and probably should:

• common.Types.NativeToValue
• packages (the whole package, really. what is it for? an example would be good.)
• checker.NewStandardEnv
• checker.StandardDeclarations
• types.NativeToValue

Oh, and in the types package, what is DynType? A lot of the others are fairly obvious, but this is all I can find on it:

var (
	// DynType singleton.
	DynType = NewTypeValue("dyn")
)

// IsDyn indicates whether the input ref.Value or ref.Type is equal to DynType.
func IsDyn(elem interface{}) bool {

Thanks for the pointers. We're working on cleaning up the docs and proto usage over the next quarter.

The concept of dyn comes from the CEL specification. It's basically a keyword to indicate that a value has dynamic type and is useful during the type-unification logic in the checker
