Re: Expansion of a macro

[Panicz Maciej Godek]

Or you can (use-modules (system base compile) (srfi srfi-11))

and then

(define* (expand-form e #:key (opts '()))

  (let-values (((exp env) (decompile

                           (compile e #:from 'scheme

                                    #:to 'tree-il

                                    #:env (current-module))

                           #:from 'tree-il

                           #:to 'scheme

                           #:opts opts)))

    exp))

(define-syntax-rule (expand _expression_)

  (expand-form '_expression_))

-- at least in guile 2.0

Sometimes it is also instructive to use the macro stepper shipped with Racket:
