Should the correct output to be
table(1 = "1",1 = "2")
?

Sorry for not including an example:
T ==> ALIST(INT,STRING)
t := table()$T
t1 := concat([1,"2"]::Record(key:INT,entry:String),t)
t1 := concat([1,"1"]::Record(key:INT,entry:String),t1)

I didn't want to remove or replace cons. So the guideline
here is to prefer concat

Yes, unfortunately this should stay. Compare:

There is some progress. If you could create a branch I'd clone/pull.
I think that the concpet will work, so we might start filling in the details
(Makefile.in etc.).
The fricas/src/doc/tmp folder corresponds to the tex_orig/. Some further remarks
below (between).
1. convps.sh ==> converts ps/*.ps
Well, seems this default simplification "(exp(a))^b --> exp(a^b)" will
break many tests, I'll not go further.
So "exp(4)-exp(1)^4" will not simplify to 0 by default, we'll have to
live with it.

Now with this patch, another problem emerges:
exp(1)*exp(1)^2 will no longer default simplifies to exp(3)
but exp(1)*exp(2). Should we add default simplification
that transform exp(a)*exp(b) to exp(a+b) when a and b
are integers?

A small problem:
For 'a^(-n)', if n is positive integer, then we represent it as '1/a^n'.
If n is an expression, then we represent it as 'a^(-n)'. In the mean
time '1/a^n' is represented as is.
So 'simplify' can't simplify 'a^(-n)' and '1/a^n' to the same thing,
that's not a problem, right?
