You could also move some checking time to the users machine. At the time
the documentation is rendered, the commands in ++E are executed and
compared internally with the ++R stuff.
Since execution might take some time, first show the ++R output and
spawn a background process that compares the
process to filter out the ++E/++R testing syntax lines automatically.
The only thing where I am not so sure about is whether ++E/++R is the
best syntax. As you may have seen in the ++ or +++ documentation, some
people dont put a space after the last + so you parser might get confused.

Having types, Axiom should actually allow you to specify what you want.

In my case, I consider x and y in fact as formal power series in t
themselves, and I think I also want that sqrt(x^2)=x.
Replace x by the formal power series in t having only the constant term -1.

factorial is very common for *my* use of CAS :
50% of numerical analysis, 50% of algebraic transformations.
And all? other Computer Algebra System uses ! for factorial.
I feel that ! is the standard function for factorial.
I remember a first play

I am sure you don't want that.
We have

Hi Tim,
I know that documentation is one of the most important things for the
Axiom project, but your approach to fixing bugs is just strange.
Suppose you have software A which has very few documentation and it has
a bug B.
You can produce from that two systems A1 and A2.
A1: Fix the bug
About the next axiom workshop: Is there anything planned to coincide
with the upcoming ISSAC meeting (July 2008?) at Risc?
No, not coinciding. But there are plans to have a
Aldor Axiom Workshop 2008
during the RISC-Summer at July 24-26, i.e. right after ISSAC.
Ralf
Yes exactly, although I am not sure why we need both Cross and Record.
Elements of Record are mutable, elements of Cross are not.

PS: Shouldn't this discussion go to axiom-developer instead of axiom-math?
