sets.filter?

[Gerrit Holl]

Hi,

would it be a good idea to add a .filter() method to a set object,
which behaves like the builtin filter() but resulting in a set?
I often see myself doing sets.Set(filter(f, someset))... Would this
be a good addition to sets.Set?

yours,
Gerrit.

the river and leap into the river, if he sink in the river his accuser
shall take possession of his house. But if the river prove that the
accused is not guilty, and he escape unhurt, then he who had brought the
accusation shall be put to death, while he who leaped into the river shall
take possession of the house that had belonged to his accuser.

Yes, it'd be a great idea. filter/map/reduce should've been methods
on sequences from the beginning.
