Issue #7335: FiniteSet not accepting iterables

[Amit Saha]

Hi,

I only am realizing that I cannot do FiniteSet[1, 2, 3, 4]) any more.
I did find it very useful to create a set from the elements of a set.
Anyway, it's probably way late for that.

So, what is the recommended way now to create a FiniteSet from an
existing list or any other iterable?

Use case: the elements of the set are calculated at run time and are
not known apriori.


PS: The release note for 0.7.6 does not contain an entry for this change.

Thanks,
Amit.

set => list

FiniteSet(*[1,2,3,4]) or FiniteSet(*set([1,2,3]))

Indeed.  Fixed.

This was an intentional change. The previous way made it impossible to
create things like FiniteSet(FiniteSet(1, 2, 3)) (a set containing a
single set).
