Compiling multiple executables with -make
I am very happy with the -make option. However, I think it could be improved even further. I would like ghc to be able to compile multiple executables with one invocation of ghc, using the -make option.
Compiling multiple executables in one invokation could safe a lot of compile-time, when the executables shares most of their source files. I believe the time would be saved, as it would remove the need to check all source files for possible recompilation for each executable. Furthermore, we would also only need to build the dependency graph once.
