[ghc]

No, I'm a long-time Linux user. I don't install G++ because I don't need it (I work in Haskell and Python) and I try not to install unnecessary packages or remove them when I'm finished. You do generally need gcc (or clang) in Linux, but not all distros distribute g++ in their gcc.

I don't think you really understand what GHC is. GHC can compile Haskell down to C or Assembly, and has an FFI to make Haskell embeddable in C. The runtime for GHC is not like the runtime for Java or other VM/Interpreter-based languages...Haskell can be compiled and embedded to turned into a shared library to be distributed with your code.
