Comment:
Jori,
When you change the milestone to wontfix, please change the status to
`positive_review` at the same time.
About the `(a,b,c)` instead of `((a,b),c)` thing: it is not that
complicated to accept such input if you need it:
{{{
sage: def a(*args,**kwds):
....: print args
....: print kwds
....:
sage: a(1,2,3,5,labels=True)
(1, 2, 3, 5)
{'labels': True}
}}}
In this case, "args" will be a list of posets that you need to transform
into a big poset, and `kwds` will be the union of all "named" arguments.
Two things to pay attention to:
1) When building the final poset, it is best to do it all at once and not
two by two (faster)
2) Always check that `kwds` does not contain something unexpected.
Otherwise, this function would say nothing when you call
`a(1,2,3,labelss="True")` and it is painful to find such typos when you
have a bug in your code.
