It's easy to just assume your tool works for you & it's the right pick, but precious few developers a) actually know computing well enough to assess the field of options, b) have any idea what they're buying.

It's heavyhanded bias that you've disregarded other options, and called whatever you think of as "best" and left everything else as "works ok all the time."

I see the small suite of built-ins as the "works ok", and not even "all of the time," just, for a couple small specific use cases. Learning about metaprogramming, ASTs, code-rewriting is a lifelong opportunity to get better, to understand what we really do when we write code at whole new levels, and those tools we truly, that truly fit the problems we actually have are the best tools.
