Hello,

I would appreciate very much if somebody could add the following thing
to the symmetric functions in sage. Mostly this is just a variant of
the omega function, which is implemented by transposition of
partitions in the schur basis. The point is that I just do not dare to
do it myself... This would mean creating a patch, and I'm afraid I
will be lost if I have two patches of my own. One is hard enough :)

My need :

a function "f.suspension(t)" where f is a symmetric function and t is
an element of the base ring.

what it should do :

in the Schur basis : it transposes the partition and multiply the
coeff by (-t)**(n-1) where n is the size

for example

a=s([3,1])
b=a.suspension(t);b
t**3*s([2,1,1])

Thanks for your help,
Frederic
