This was my first thought, although it comes from my POV where I think I am a slow learner because I can't pickup a new programming language over a weekend. I'm still exploring the dark corners of C++ after a year or two, but mostly that's due to the demands of the current and previous project. I went through the whole Python tutorial once, to never use it much again, then flubbed a Google on-site because of it. On the flipside, when given a week to work up some post-proc analysis code and the opportunity to do it Python, I was up and running in a little less than a day. It's amazing what you can do when you have access to reference materials and more than 60 minutes.
