Python Functional Programming with Python

Multi-line Lambdas

When Kenneth showed the hack for multi-line lambdas i thought for sure he was going to implement the '\' approach but he did not. In my python interpreter though I experimented with both approaches and they both seem to work.

Is using the '\' character an acceptable way to implement a multi-line lambda?

Acceptable probably isn't the right word since multi-line lambdas seem to be generally unacceptable, you would then just want to right a normal function but yeah, does that work in most cases or will the '\' approach break stuff unexpectedly?

It's more about readability. PEP-0008 allows using a \. But in most cases, using parens to create a container is the preferred method for multi-line statements (including lambdas).
