"Any serious programmer should be a polyglot by default." The language itself is not usually a problem for me. I mean an array is an array in any language. It's environment. Example: c# (which I think in MS's best work, by the way); c# was easy to pick up. The .Net framework was another matter. That took time. Knowing where the resources are and hell - even getting comfortable with the documentation and the IDE took time. So now, when I hire a programer, I'm not too interested in his language skills. I'm assume he can code well enough not to embarrass himself. It's his knowledge of the environment that we run. That's what I look for.
