I recently encountered an issue with a module name that was not found in the modules list for an out of date standard fcl in dune for one of the prototype experiments. The expression of this was a standard library exception.

%MSG-s StdLibException:                           
Standard library exception caught in art          
map::at                                           
%MSG                                              
Art has completed and will exit with status 66.  

I tracked the exception down to prune_configuration.cc:273, showing a module was left in our fcl that is no longer configured. The result is a "module_name" which is not found in the "modules" map, causing the exception. It would be helpful for art to report this back to the user. I request a more detailed output when a module_name is not found in modules, including the name of the module that was not found.
