// Package aliases defines backward compatible shims

// This defines placeholders for x/tools until 1.26.
// NewAlias creates a new TypeName in Package pkg that
// is an alias for the type rhs.
//
// The enabled parameter determines whether the resulting [TypeName]'s
// type is an [types.Alias]. Its value must be the result of a call to
// [Enabled], which computes the effective value of
// GODEBUG=gotypesalias=... by invoking the type checker. The Enabled
// function is expensive and should be called once per task (e.g.
// package import), not once per call to NewAlias.
//
// Precondition: enabled || len(tparams)==0.
// If materialized aliases are disabled, there must not be any type parameters.
