Yes. Yes, that exactly solves my problem. *sheepish look* Thanks. On Tue, Aug 9, 2016 at 8:47 PM, Matthew Butterick wrote: > > On Aug 9, 2016, at 7:52 PM, David Storrs wrote: > > > This solves the problem of creating top-level bindings at run time

Re: [racket-users] How to dynamically generate top-level procedures?

Here's something in the ballpark. #lang racket (define-namespace-anchor nsa) (define ns (namespace-anchor->namespace nsa)) (let ((xyz 1)) (for ((name '(x y z))) (namespace-set-variable-value! name (lambda () (displayln (format "~a: ~a" name xyz)) (set! xyz (add1 xyz))) #f ns))) (eval

[racket-users] How to dynamically generate top-level procedures?

In Perl it's possible to generate main-namespace functions like so: perl -E 'my $z = 1; for (qw/foo bar baz/) {my $x = $_; *$_ = sub{ say "$x: ", $z++ }}; foo(); bar(); baz();' This outputs: foo: 1 bar: 2 baz: 3 Note that it is generating top-level subroutines that can be called from
