How can I make an identifier that will have a certain binding no matter what
phase level it's referenced at?
For example if I’m making a reader extension that will produce a lambda
expression, how do I make it so that the lambda expression will be able to
exist at any phase level?
For example this program using #lang rackjure doesn’t work:
#lang rackjure
(require (for-meta 1 racket/base)
(for-meta 2 racket/base)
(for-meta 3 racket/base)
(for-meta 4 racket/base)
)
#λ(* 2 %) ; works, produces approx. (lambda (%) (* 2 %))
(begin-for-syntax
(begin-for-syntax
#λ(* 2 %) ; lambda: unbound identifier at phase 2;
; ; also, no #%app syntax transformer is bound in: lambda
))
Is there any way to construct an identifier that would be bound to lambda from
racket/base no matter what phase level it’s used in?
