I came across 'bundler/inline' in Bundler pull request 3440, which I'd found from Rails pull request 20429. This now has a little snippet on the What's new page of the Bundler site.

This little example demonstrates how I might use it to create a single file using minitest.

I've just noticed that this script was working for me because I already had minitest installed as a system gem. If I uninstall the gem then the script fails because it can't find minitest. The source code documents an option to install gems if they don't exist (gemfile(true) do) but that doesn't seem to work for me. I see the following error:

Fetching gem metadata from https://rubygems.org/...
Fetching version metadata from https://rubygems.org/..

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.
