Steps to reproduce this
Steps:
  1. Use print() with more than 1 arguments will cause FES to print an incorrect message
    🌸 p5.js says: Expected at most 1 argument, but received more in print(). For more information, see https://p5js.org/reference/p5/print. 
    
  2. It should not be printing that message as print() like console.log() accepts any number of arguments. This should either be fixed in the reference and/or in FES parameter validation logic itself.
Snippet:

function setup() {
  createCanvas(400, 400);
  print(1, 2);
}

Research direction

Start with the print() implementation and its Friendly Errors System parameter validation, using the provided setup() snippet with print(1, 2) to reproduce the message. Compare the validation with print()'s documented behavior and update the relevant reference or validation logic so multiple arguments are accepted without the incorrect error.
