This is probably a "me problem," but I have had a hard time moving beyond the tutorials to actually getting work done. For example, I am working on a project right now where I would typically use a dict of dicts in python and then use map functions so that I can process the keys in parallel. When coming to python from perl, ruby, and c++ I found that I already had a pretty good intuition about how this would work.

I read the documentation, but could not make as much sense of it as I should. I searched online for example and found a few hits on the question, but not nearly as many as I would in other languages, and if there were answers then they were often marked "wrong," or I could not get them to work with my code.

After a lot of searching and trial and error I finally got that working, then started looking into how to run this on multiple nodes and processors and got completely lost.

I am sure the documentation is there and that I could do a better job figuring it out. I am also sure Julia would be a great match for the type of work that I do, and I am going to keep trying. But from what I have seen so far it feels like the pain of trying to migrate from Python to Julia is pretty difficult to justify.
