When using syntax/parse, is there a good way to do something like this?
(define-splicing-syntax-class options
(pattern (~seq (~or (~optional (~seq (~and #:a a?)))
(~optional (~seq (~and #:b b?)))

I think user-friendly 500 page should be designed separately just as web
devs do for 404 page.
In practice, a user happens to meet an uncaught runtime exception, and he's
browsing a buggy website,
perhaps he do not have the will to report the problem, nor the way to
report it.
Finally, devs will
For the purposes of the Web server, I don't think that's the right
thing to do. The right thing to do if you don't like the error display

I was thinking the parameter could be a handy runtime switch,
defaulting to safe. However realistically there's probably a lot of
other ground to cover when it comes to debug vs. production
deployments. Maybe this needs a more comprehensive approach than
nibbling away one switch at a time.

Alexis, think of a lazy sequence as something that the rest of the program
will explore. In addition to a GUI-based exploration, I would love to see a
programmatic one. Imagine
(explore-lazy lazy-sequence:exp strictness-pattern:exp)
