> Ruby does not require you to put the opening and closing parenthesis on a function to run that function, and it's not always put there when you have zero or 1

> Ruby does not require you to put the opening and closing parenthesis on a function to run that function, and it's not always put there when you have zero or 1 parameter mind = blown I always liked how functionName denotes the function and functionName() calls the function, and then it denotes the result e.g. in JavaScript or in math. But just saying functionName to call a function makes the code read more like English. Code that reads like English > code that reads like math. (And you can still talk about functions of course.)

It comes with the downside that if you want to pass the function itself around, you need to do f=something.method(:the_function), and then f.call(args). It's not a huge deal, but... meh.

  You might know this, but you can also do f.(args) or f[args] in the latter case. It's still a bit meh, but slightly less verbose.

  But in general, ruby code only passes anonymous functions and, in those cases, the syntax is beautiful.

You'd like the ML-family languages, which don't use parentheses to call functions.
