I’d like to directly make use of the source and create an initial, human readable template by marking up dynamic parts in an effective way.
There are nice approaches to #templates for formatting #output. I’d like to find something similar for #input without reinventing a crutch and calling it a wheel.
(Yes, in an ideal parallel universe every source has a switch to output structured data.)

I’ll have to have a thorough look into existing ways of templating output, first. (2/2)
