del and sets proposal

[Lawrence D'Oliveiro]

Would it really be "confusing" if sets used the same interface as dicts
use? I don't think so. What else could "del aset[x]" mean other than
"delete element x"?

Yes, but "x" in what sense?

The only sense possible.

There is no precedent for using a set element as a subscript to the set.

 

[Henk.van.Asselt]

"Life was like a box of chocolates. You never know what you're gonna
get."

Regardless of how it is implemented, mathematically a set is a
collection of items.
The order does not matter, an item is part of a set, or is not part of
a set. Period.
