If a project consists of both a library and executables, the library modules are re-compiled for each executable. (I use GHC.) That leads to high space and time consumption. Is this a bug or a feature?
A package that has both a library and executables isn't supported well right now, and in fact the intention is to deprecate and remove it. Actually I'm surprised if it works at all.
The right way is to have a separate package to contain the library code, and depend on this package for your executables.
Sounds good. Btw. that's the way the Modula-3 build system handles packages. Ask Luca Cardelli in Cambridge! :-) Maybe the attached executables are the interim solution until "the right thing" (compiling multiple packages easily) is implemented.
