I've adjusted the bytecode compiler so that it can deal with more local
types. To exercise the changes, fixnum results are tracked like flonum
results, although the JIT doesn't currently take advantage of fixnum
annotations.
Now, it should be easy to add
#define SCHEME_LOCAL_TYPE_EXTNUM 3

This "Supercomputer Toolkit" looks pretty cool! I skimmed over the article, and
will read it completely later on. Am I understanding that this uses integer
arithmetic? It said that it supported quad-precision 128-bit integers (four
32-bit integers concatenated).
One of the cool things about For

Do not take the contents of SICP as Scheme canon.

My understanding of Scheme, including Racket, is that types get converted
automatically without explicit casting. This is not an add-on for the language,
but is inherent in the language. For example:
(/ 10 6)
5/3 this is what Gambit does

Thank you for the responses Vincent and Neil.
Neil, thanks for the information here-I will meditate on this and how to
utilize it.

Is this expected behaviour?
I'm using the customization example in the documents
When I add this line instead of the last line
;(menu-bind "c:a" "Run")
(menu-bind "c:x;k" "Close")
all the existing control-x bindings go away.
So once I do "Edit->Keybindings->Add user-defined ..."

Congrats.
The Java guy should have a UML model and a couple of patterns like a
HelloWorldFactory and a HelloFlyweight built in, too. giggle.

It is a pleasure to share some news about Realm of Racket with everyone here.
The complete draft has gone to the NoStarch copy editor, we are putting on the
final touches, and we have taken our first video live:

Stay tuned. More videos, more news, more pa
Eric, Hugh,
OOP surely is not what we chose Racket for.
This can lead to a lengthy discussion about the definitions of OOP,
level of support of OOP in Racket according to those definitions,
usefulness of OOP for different kinds of tasks, etc. I think we
better skip the whole OOP topic here.

Seems to me that Moore and Rather used Moore's FORTH at the National Radio
Astronomy Observatory before they started Forth Inc. So you might say that
FORTH is a 'natural' for Astronomy!

If would be OK in terms of numerical accuracy, but
I feel that it would not be good in terms of performance.

Sorry, I feel the need to add my 2 cents to this.
