I'm a little late, I just read the post today but I replicated your DSL using the Scheme dialect of Lisp: http://neverfriday.com/blog/?p=43 What do you think?

Sorry; I wasn't sure if your comments permitted formatting. Here's the Rebol code: site: http://www.example.com forever [ prin [now "Checking site... "] either exists? site [print [site "ok"]] [print [site "ERROR!"]] wait 0:03 ]

Quite a few languages do this kind of task with no DSL fanfare at all. Here's a version in normal Rebol code: site: http://www.example.com
forever [
    prin [now "Checking site... "]
    either exists? site [print [site "ok"]] [print [site "ERROR!"]]
    wait 0:03
] Rebol is an example of dynamic languages in general (ruby, python, perl), but it is specifically designed to support building of DSLs.

I will admit that "simply changing the lang" takes some time of getting used to :-)

Thank you for taking the time to explain this Oren, I really appreciate it :) I've got to admit "we simply change the language" makes my head spin a bit! I'm going to dig through the Rhino-DSL source now :)
