When they want to develop a large multi-module D program they must know something about how a linker works. But D has to scale down to smaller programs too, where there are only one or very few modules, written by not experts of C-class languages. In this situation more readable error messages, produced by dmd that catches a basic error before the linker, is probably useful.
