Well, I guess I'm a slow learner; I reckon on it taking me a minimum of 6 months to become competent in a new language. It's not just the syntax and the libraries; every language I've ever used has had heffalump traps, but even if there are no traps, you still have to become sure there are none.
Most programmers I've worked with have become comfortable with a new language much faster than me.
