I don't think the title and the article really communicates it's case well. Did not understand the goal until 90% through the article when they showed the source code of RCL with the loops.

This isn't syntax vs abstraction. This is how much programming language power do you want to enable in your configuration language. This is a big difference and I think we miss the interesting part of that discussion because we dip into this 'abstraction angle.

I think if people want a more powerful, programmable config language, maybe they should use something like Lua or Scheme instead of reinventing the wheel with those new niche languages.

The "abstraction angle" seems to be a different encoding for "power of configuration language."
