In my early days, I identified strongly with my chosen programming language, but people way more experienced than me taught me that a programming language is a tool, and that this approach is akin to saying "well, I don't know about those pliers, I am a hammerer."
My personal feeling from working across a wide range of programming languages is that it expands your horizons in a massive way (and hard to qualitatively describe), and I'm happy that I did this.
