It was written to be able to have lexical handles and pass them around.
With the above implementation you don't need to read a 600+ line module
to have every file action go through methods that are not needed at
all, and you also do not have to read the documentation for the
deviating syntax. I'd rather stick to simple, easy and standard.

Because it is more efficient? And yes, it reads better, because it is
used in a zillion places already.
