The question is:
How do I report warnings when I use the wrong number ("less than" in my case) of arguments for a user-defined function? I'm sure there is a way to do this but I do not know what option to turn on.
Example: I have a function f[x,y] defined
but I keep entering f[x] instead.
I know that generally it is not an issue since the function remains as f[x] symbolically (when you continue to use the function in other inputs), but I'd like to make it more clear that I did something wrong.
