→Function overloading

As you can see, the basic idea is pretty simple and also scalable, you could easily extend this to and also return different types of values, such as vectors or hashes. This could for example be used to create wrappers in Nasal space for doing 3D maths, with vectors and matrices, so that a matrix multiplication could return a new matrix, too. | As you can see, the basic idea is pretty simple and also scalable, you could easily extend this to and also return different types of values, such as vectors or hashes.

Another common technique to "overload" a function is to get a handle to the original function and then re-implement the function at your script's scope, so that calls to settimer/setlistener will automatically invoke your own version of the function, this is explained at [[Developing and debugging Nasal code#Managing timers and listeners]]. | |||
