I think the XML parser should be for parsing XML. You could look at
the HTML module or, even better, use Neil van Dyke's html-parsing
library, which deals with this issue and more.

Hi,
In HTML the tag has no end tag. This causes trouble while using
string->xexpr. It is reported that tag img is not closed.
I found in the XML writer there is a parameter named empty-tag-shorthand to
control the HTML generation behavior. So I added a quick hack into XML

Have you been able to find the example in the documentation?

A good example, it is like map, but for when you only care about side
effects.

I don't know if it's a particularly good example, but here's a basic usage
of for-each:
#lang racket
(define lst '(apple banana cherry))
(for-each
(lambda (x)
; x is bound to each item of lst in turn
(printf "item:~a~n" x)
; do something more with x
)
lst)

The way it is now -- file on top and instarepl at the bottom -- is ok. But I
was wondering if the instarepl view could be also set so it is vertical as
well. Somewhat like a split screen view.. At least, for me, having that
vertical view makes it easier in terms of reading and comparing.

It may be worthwhile; I haven't looked at all into RubyMotion though.

Using this thread is fine, because I'm monitoring it closely.

Everyone counts. Once you have programmed in this world for a while, however,
you won't really see the parens anymore and you won't make nearly as many
syntax mistakes as in 'ugly languages'.

There's something quite basic about how scheme works that eludes me.

This program works as I expect:

FWIW, big GCs are usually multiple seconds. But minor collections are

BTW, I seem to remember that GMP stores the table of small primes as a

Let's see... there are 50847534 primes under 10^9, the max difference
between a consecutive pair of them is 282. We can store that
