Hi Martin,
without looking into topology.spad I guess the reason for you problem
comes from the line
h : Homset(source,target) := homset()
Thanks Ralf,
I have just tried what you suggested and I think you are correct.
As you suspected, this cleared the problem once it happened:
)clear prop h
and calling it this way:
h := homset() $ Homset(source,target)
does not create the problem.
I would never have worked this out without your help. Are there any
resources that would help SPAD programmers solve issues like this? It
would be good if there was information to help with debugging on
fricas.github.io
Many years ago, I tried to collect information that would help me with
debugging and put it here as I found it:
https://www.euclideanspace.com/prog/scratchpad/spad/debug/index.htm
But that is just my random notes which may be incorrect and out-of-date,
if there is anything useful to others it would be good if you could put
it on fricas.github.io
Thanks again,
Martin
