A decent editor should provide some sort of completion facility on
previously typed terms, so that you don't have to retype them.

For example in Vim having first typed:

  use My::Really::Long::Module::Name;

you can then type:

  my $obj = M

Pressing Ctrl+P ("P" for "previous"; you can guess what the keystroke
for "next" is) completes this, incorrectly, to:

  my $obj = Module

But simply keep Ctrl pressed and tap P a second time and you get:

  my $obj = My

And from there press Ctrl+X Ctrl+P to type the word following the one
you've just completed, giving:

  my $obj = My::Really

Do that a few more times and you've got the whole name:

  my $obj = My::Really::Long::Module::Name

That sounds tedious when written down like this, but basically it just
involves holding down Ctrl and pressing P and X a few times.

I believe that Emacs has an equivalent feature, and I'm sure I've seen
some kind of tooltip completion feature on a gui Windows editor.

Picking a decent editor and learning how to use it well is far better
than trying to use unnaturally short identifiers throughout your code!

But why group them under either?  Why group them at all?

That's along the same lines of why I'd prefer CAD::, Graphics::,
Video::, and whatever -- cos those are the sorts of modules that work
together (even if only some of them are to do with file-types), rather
than all the modules dealing with file-types.

May God bless us with enough foolishness to believe that we can make a
difference in this world, so that we can do what others claim cannot be done.
