Drush Enable a module and all its submodules
There is nothing out of the box to automatically enable submodules, but it is, in fact, possible to specify similarly-named modules via a wildcard:

drush en 'coder*'


As previously mentioned, this is only useful in certain niche situations.  I have never used it in any practical situation.  If you happened to need it, it would be just the thing, though.
