There is already an if() "statement", it is a function. As I remember, 
the syntax is like this: if(CONDITION, IF_VAL, ELSE_VAL)
Support for variables and other flow control would be very useful, but I 
suspect it would require rewriting a large portion of the function code. 
I don't understand much of it though, I could be wrong.
