Option wrappers for slices and maps?

[renom]

Something like:

var s OptionSlice[[]int]
var m OptionMap[map[string]int]
fmt.Println(s.IsPresent(10), s.OrEmpty(10))
fmt.Println(m.IsPresent("key"), m.OrEmpty("key"))

I think you should use github.com/samber/lo instead.

• lo.Contains
• lo.FindOrElse

[renom]

lo.Contains and lo.FindOrElse checks for a value, not for index/key

[renom]

returning the default value with OrEmpty would help avoiding out of bounds error for slices
