> One of my favorite things to show

Who have you shown this to? What kind of person is impressed by this? Anyone that programs in any other language already knows that syntax is fungible so who cares if C chooses to use addition and brackets this way. So the only people that might be impressed by this are people who don't program. In which case why are you showing them lol.

For example (assuming you're a C programmer) are you impressed by this python syntax

  [a] * 3 == [a, a, a]
