Been doing a task recently that I find myself really wishing I used python for. I've lately been writing software to migrate files from servers up to Azure. I picked Scala because I pick Scala for everything. The task involves making some system calls (converting .rar archives to .zip), and a number of other string massaging type tasks.
Scala is really great for writing complex software because you get a really fast, trustworthy feedback loop on correct vs. not correct, but for this particular task, the feedback loop is terrible. It's easy to get it compile, but to test in-situ I've got to bundle it up and ship it out to the server, so the feedback loop is just terribly slow. I can't install dev tools in-situ, but could modify python scripts with a text editor.
In retrospect, Python would have probably quartered the dev time.
