Yes, it does.

Agreed.

But this should not be an excuse to not provide means for writing 
code that's simpler to read. We could try to build a library as a first 
step, something like (naming to be discussed)

require 'mainfile'
in_main_file { ... }

Those who are bothered by the current implementation (as I am) 
could use the library, the others don't have to.
