Title: Change the diagnostic for wrongly imported modules

This was filed just recently:

http://stackoverflow.com/questions/23020537/weird-error-when-importing-module

It's not the only time, I've seen users being confused by the diagnostics frequently (even though I think it was me who introduced this diagnostic the first time around). I think listing explicitly how to import the module should make everything clear.
