You might argue that that's a "compiler" that you install, but:
a) a programming language is a purely theoritical concept without a compiler
b) for some languages language+compiler is one and the same. Either they don't have a spec, or there's only one compiler. Swift is such a case.
sudo apt-get install ghc
