The code generated by a macro automatically adopts the lexical context at the
macro-definition site. So is this not analogous to your Perl code?
;;;;;;;
#lang racket
(define z 1)
(define-syntax-rule (makefuns name ...)
(begin
(define (name)
(displayln (format "~a: ~a" 'name z))
(set! z (+ z 1))) ...))
(makefuns foo bar baz)
(foo) ; prints "foo: 1"
(bar) ; prints "bar: 2"
(baz) ; prints "baz: 3"
