Your code looks better.

My (probably controversial) opinion on this is that the idiomatic D solution for those text "scripts" is to use a scripting language, as Python :-)

In this case a Python version is more readable, shorter and probably faster too because reading the lines of a _normal_ text file is faster in Python compared to D (because Python is more optimized for such purposes. I can show benchmarks on request).

On the other hand D2 is in its debugging phase, so it's good to use it even for purposes it's not the best language for, to catch bugs or performance bugs. So I think it's positive to write such scripts in D2, even if in a real-world setting I want to use Python to write them.
