Function Calls
In GCScript, every function returns a value. (Even a 'void' function returns a value, which is always null.) However, in many cases, the return value isn't significant, or is only a byproduct of the function's primary purpose. For those kinds of functions, you can simply call the function as a statement, and ignore the result value.
Example
Print('Hello'); // We call the Print function because of its // effect (of printing something to the script // console window), not because of its result // value (which is always null).
