Functions

Functions are declared using the fun keyword and then the name of the function. After that, the parameters are listed within brackets as per the example. The return type is contained within the open function block arrow. To return from a function, use the return arrow <--.

fun add(a -str|dec-, b -str|dec-) =str|dec=> <~~ str|dec means string or decimal types accepted / returned
	<-- a + b <~~ returns a + b
