I do compilers, low level OS stuff, debuggers, code analysis tools, so I'm always having to switch languages or keep up with other languages. When I have more of a choice my current preferences are a mixture of C++14, Perl and Assembly ( especially PowerPC ). Modern C++ is a pretty nice language and I consider it distinct from C++98 and earlier. I also have way too much fun playing with meta-programming when I can. And template meta-programming is always fun for adding another level. Wrote a binary object file parser once that was pretty much all default member initializers ( thanks C++14 ) and template meta programming. Why write a function when the compiler will do it for you, especially when you are writing another compiler.
