Thanks for taking the time to reply. Using a variable of require is a good
idea.
Referencing variables as X::Size seems verbose. Is there any way for require
to define a set of local scoped variables so the ERB template could drop the
X:: prefix?

Not sure if I totally understand your question, but I'll try to help.
Note that if you want to, you can make your require use a variable so that
you can vary which file to require in.
Also note that you can do your require and include in the module that calls
erb since you can pass in a binding. The binding gives erb access to
everything that was available where ever the binding was created. So you
don't have to put the require and inlude in the erb template.
