Thanks for reply.
(require (for-syntax ...)) is what I actually needed.
I don't know why I did not try this first , and I read the guide about
this few hours back.
Just for information by adding #:omit-define-syntaxes in:
(begin-for-syntax
(struct proc-struct (name args loe)
#:omit-define-syntaxes))
I get error :
"expand: unbound identifier in module (in phase 1, transformer
environment) in: proc-struct "
But this works :
(begin-for-syntax
(struct proc-struct (name args loe)
#:omit-define-syntaxes #:constructor-name make-proc-struct))
Thanks again
Veer.
