If memory serves me correctly we had trouble passing off some module names
to some OTP modules that liked to use the {M,F,A} "callback" idiom.

But there may have been some problems with some 3rd party tools as well.

And we inherited a build system from someone and it did not like the dots
either.

Sorry I cannot recall any specifics.
