<p class="MsoNormal">I’m experimenting with trying to use separate module maps in my three include directories, as a possible alternative to my one module map approach in a common parent directory.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Isn’t there some way we could support cyclic dependencies in building modules?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems that cycles are okay in sub-modules, but not in top-level modules.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems the only way to work around having cycles in separate directories is to make lots of smaller top-level modules. But then because they are not submodules any more, cycles within an include directory start popping up. For example:<o:p></o:p></p>
