So, I was under the impression that the REPL was the toplevel (unless
you entered a module context or something like that). But I just had
something challenge that assumption and so now I'm a bit confused.
I have the following top level program:
(begin
(require (for-meta 1 racket)
(for-meta 2 racket))
(begin-for-syntax
(begin-for-syntax
(define x 5))))
When I run this top level program in the REPL, it works just fine. And
I can even reference x in later evaluations. (Provided I'm at the
meta-level of 2).
However, when I pass this top level program into compile like so:
http://pasterack.org/pastes/38556
(compile #'(begin
(require (for-meta 1 racket)
(for-meta 2 racket))
(begin-for-syntax
(begin-for-syntax
(define x 5)))))
I get the following error:
define: unbound identifier at phase 2;
also, no #%app syntax transformer is bound in: define
Can someone give me the reason (or at least some intuition) as to why
this works in the repl, but not at the top level?
Thank you.
