Yes, this is what Nix offers. You can trivially have have multiple versions of stuff installed without conflicts. Personally, I have multiple versions of the GHC Haskell compiler, Clang/LLVM, Go, Node, etc. In fact, I keep shell.nix file in each of my repositories at work, and all I have to do is $ nix-shell in each project root and -- like magic -- I have all of the compilers/environment-variables/etc setup for work. Meanwhile, outside of that terminal window, my system is untouched. Nix is quite different from just about any other package manager out there. If there's something that seems unfeasible or impossible, please feel free to ask specific questions to challenge my assertions. Nix is so different that it will be tempting to think "surely he means... no, that can't be possible, he must be mistaken... but how would that work?" Rather than silently thinking those things, please feel free to skip right to asking "how?" (For more details, see also my long post to your original statement/question)
