#print(*args) ⇒ Object

Callers of this routine should make sure to use comma to separate format argments rather than %. Otherwise it seems that if the string you want to print has format specifier, which could happen if you are trying to show say a source-code line with “puts” or “print” in it, this print routine will give an error saying it is looking for more arguments.
