Hi List!
I'm a particle physicist just getting started with some julia. I've been using some python in the past but now I'm trying to use analyzing some lab data as an excuse to learn Julia. So far it looks like I'm going to stick with it for a while. I've been trying to play with basic image analysis, and I've come across the following behavior: append! complains that it doesn't find a suitable method for my call signature, but it does append an #undef. Is this intended?
