Hi all,


For those, who like functional programming, this library [1] provides the following way of functional composition:

```python
from friendly_sequences import Seq

assert (
Seq[int]((1, 2))
.zip(Seq[int]((3, 4)))
.flat_map(lambda x: x + 1)
.filter(lambda x: x != 2)
.sort()
.map(str)
.fold(lambda left, right: f"{left}{right}", "")
) == “345"
```

It depends only on "attrs>=21.3.0”
