Cyclic imports are a problem for the .NET implementations.  This is a
general problem with using assemblies to hold both the interface and the
implementation.  The programmer must ensure that they don't introduce a
cyclic dependency.  Note that mmake will report a cyclic dependency warning
and that combined with the failure to build a file because of a missing
assembly should be enough for the programmer to debug the problem.
