So, for what it's worth:

Otherwise, yeah. I'd love to be able to define interfaces with extra
methods for implementors, but if you arrange your code around "traits",

Uh, you should check the code:
github.com/jackc/pgtype/blob/master/float8.go If you know what you have and
what you're dealing with, and if you actually check the error result, you
do get safety. If you don't know what you've got, or if you're iterating
through the values, then you end up hitti
Sorry, the predicate should be
var b T
pred := func(a T) bool { return cmp(a, b) >= 0 }

Hm I must say, I also don't really understand removing the predicate-based
one. It is easy, when you have a comparison function, to get to a predicate:
pred := func(a, b T) bool { return cmp(a, b) >= 0 }
But not the other way around, so a predicate is more general.

I think that playground is broken.

The earlier method signature for slices.BinarySearchFunc was very useful:
It was of the form
```
slices.BinarySearchFunc(array, func(e T) bool)
```
which returned the smallest index at which predicate would return true.
This was incredibly useful to do inequality operation binary searches -

I was really annoyed that, apparently, I accidentally deleted the message
you're replying to, immediately after writing it.
I agree with you about being possibly surprised by values of outside of an
expected range. The benefit of the above is merely that accessing it is
guaranteed to be checked
in case anyone get's here and is confused...
you can wrap the additional functionality in the struct and use the
interfaces from before

Hello gophers,
We plan to issue Go 1.18.1 and Go 1.17.9 on Thursday, April 7th.
These minor releases include a PRIVATE security fix to the standard library.
Following our security policy, this is the pre-announcement of those
releases.
Thanks,
