Ask HN: How do you manage working with multiple languages?

Everyone has a language that they love working in, but sometimes the problems at hand require different tools. This may mean writing code in 2 or 3 languages a day. How do you write great code in any language while staying true to the language's ideals and not trying to transform it to work as other languages?

EDIT: When working with C/Cuda, python, and perl throughout the day, I find myself being pythonic in perl, and whatnot, or not being pythonic in python after working in C/cuda. Then I have to go back in refactor. I'm sure I'll get used to it eventually, I was just wondering what HN does to keep their head straight.
