Carl,
you were totally right.
The results are matching your previsions. I get:
var('Cb')
G_igr_d._operands[1]._operands[1] is Cb
False
G_works = SR(repr(G_igr_d))
time G_works.subs(paramsd)

I add now another aspect: the G_igr_d is symbolically evaluated in

A belated build/test report on a 64-bit Suse linux machine. Build ok,

Dear all,
I am so glad to hear that the implicit substitutions are going to go! It
is so much clearer to write e.g.
var('a b c x')
f = a*x^2 + b*x + c
f(x=4,a=1,b=3,c=2)
rather than
f(1,3,2,4)
to get the desired result. Most people I know got burned with implicit
assumptions in Fortran
I've took a look a the example code, and so I think that the bug is
in the dumps and load function:
var('Rs')
mio = Rs + Rs*Rs + sqrt(10)

IAt this time I've not looked inside the code, but

Jason's argument is interesting. I'll think about that one; if good
math and good programming go together, it should probably be done.
Anyway, the decision is made.
But I'm not sure that x(x+1) being x+1 is as much of a problem; does x
