// Package cue is the main API for CUE evaluation.
//
// [Value] is the main type that represents CUE evaluations.
// Values are created with a [cuecontext.Context].
// Only values created from the same Context can be involved in the same operation.
// Values created from the same Context are not safe for concurrent use,
// which we intend to change in the future.
//
// A Context defines the set of active packages, the translations of field
// names to unique codes, as well as the set of builtins. Use
//
//	import "cuelang.org/go/cue/cuecontext"
//
//	ctx := cuecontext.New()
//
// to obtain a context.
//
// Note that the following types are DEPRECATED and their usage should be
// avoided if possible:
//
//	[FieldInfo]
//	[Instance]
//	[Runtime]
//	[Struct]
//
// Many types also have deprecated methods. Code that already uses deprecated
// methods can keep using them for at least some time. We aim to provide a
// go or cue fix solution to automatically rewrite code using the new API.
