For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

In GDScript, functions are not [i]first-class objects[/i]. This means it is impossible to store them directly as variables, return them from another function, or pass them as arguments.
|
|
However, by creating a [FuncRef] using the [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called.
