Recursion in RL Functions

Today I was thinking if it were possible to create recursive functions in the RL Language, so I made a small test by calculating factorials. I started by defining the function as:

function factorial(long x) returns long {
if( x == 1) {
return 1;
} else {
return x*(factorial( x-1 ));

Next, I just ran it by using:

println("The factorial of 12 is: " + factorial(12) + ".");

and this gave me the expected result of:

The factorial of 12 is: 479001600.

so, this seems to work fine.

Next thing will be to try recursion for facts, and of course for rules... More about that later.
