The error shown when the compiler fails to build a module from its textual interface has been creating some confusion. This is a proposal to make it more useful to the programmer not working in the SDK, insist on looking at the previous errors first, put less emphasis on possible compiler bugs, and always show alternatives to the incompatible compilers issue as this is the most common case now.
