Hey I asked for this a few months back and Matthew didn't grant it to
me.

I would like to write a macro that can be used inside begin-for-

in a different file and (require (for-syntax "x.ss")) on that file.
Is there something akin to (define-for-meta ...) so that I can
define my syntax at meta phase 2 and hopefully achieve the same thing?
The following won't work unless `bar' is moved to 'y.ss' (and
uncomment y.ss). There is no real need to do this other than
keeping definitions all in the same file.
#lang scheme/base
(require (for-syntax
scheme/base
;; "y.ss"
))
(define-syntax bar
(syntax-rules ()
((_ x)
(+ 1 x))))
(begin-for-syntax
(define (foo)
(let ([x 1])
(printf "foo ~a\n" (bar x))))
(foo))
