Comment (by duncan):

 It should be possible in principle to provide an explanation in this case,
 something like "Constructor `D' is not exported from module `M'. To get
 access to the internals you can reload the module in interpreted mode
 using :set -fobject-code and :reload"

 The names of the internal things would have to be recorded in the .hi file
 for this to be possible (even if there's no corresponding object code
 since it all got inlined away). Of course it may not be trivial to keep
 this info.
