Really? I took it as a "clever" hack for flattering everyone that actually indicates the author has even more to learn. To wit: there's a lot more relativism involved that one might expect at first inspection.

For me, Perl would be a "keep me alive" language. Yet I recognize that there's a lot of truly esoteric and impressive stuff in Perl. My "bread and butter" and my "hack it out" has been Smalltalk, which to a lot of people would be an esoteric "happiness" language. As it happens, it's a language with substantial libraries with which one can get some serious work done. Many languages have played two or all three roles for many different people. Also, lacking a "bread and butter" language is not a sign that someone has difficulty working in teams. It can also be a sign that someone is very good at navigating career pitfalls.

Often what a programmer thinks of a language and how they use it really says more about the programmer than it does about the language.
