I'm curious, how do you feel about PowerShell?

I think it's quite amazing in that it's basically the scripting language for dotnet. I love that it allows for interactive usage of dotnet libraries.

To me it has the feel of a lot of the dynamic languages from the past, but in a framework that acknowledges types.

I've been using it for finance/economic data stuff lately. For example:

The only downside is a lack of a Pandas-like library for it, so I occasionally reach for Python for larger datasets.
