It can. To compile a module use the "-c" ('c' for "compile"). If you
want an executable you will need to have an entry-point (which is
main).
Typically you would write your program in a file, have a main
function, and then write
ghc --make MyMainModule.hs -o MyExecutableName
Optionally adding "-O" or "-O2" for optimisation.
The "--make" flag is really useful as it will cause GHC to track down
dependencies automatically and compile them if needed (reducing the
need for makefiles etc.).
