ghc --make would be wonderful for UniForM, which at the moment consists of a large selection of libraries, were it not for the restriction that ghc --make insists on only having one module as an argument. Er why? At this rate I shall be driven to writing an otherwise useless module which imports all the modules in each directory, since ghc --make does indeed look a lot faster than compiling each module individually. (In particular, we win big here, I think because the NFS system is very inefficient and makes reading all the .hi files very expensive.) Actually I'd like to just give ghc --make a list of ALL the source files and let it figure out the dependencies. This could also include object files (compiled from C) which were to be linked in, for example.
