Do you know what year it is?

Vim auto-indents macro blocks just fine, and preprocessing isn't compilation. For your edification, clang-format is amazing: https://youtu.be/JSjoCisIHcM?t=1764

Couldn't find a probabilistic testing library, eh?

In a similar vein: https://www.destroyallsoftware.com/talks/the-birth-and-death...

The magic __COUNTER__ macro supported by some compilers can be used to simulate gensym.

Does the body have ways of shutting that down?

Subtle.

Ruby's Struct is pretty nifty.

    Person = Struct.new :name, :age

    people = [
      Person.new('Alice', 42),
      Person.new('Bob',   23),
      Person.new('Carol', 30)
    ]

    people.sort_by(&:age).map(&:name)
    # => ["Bob", "Carol", "Alice"]

    $ whatis code
    code: nothing appropriate.

"Ruby code can have a syntax error in a conditional..."

No, it can't. If this is something you've seen "many times", would you mind providing an example? Show me a program that Ruby tries to execute without having been able to parse it.
