The excellent influence of functional programming on imperative 
programming is implicit iteration and higher-order functions.

Any explicit for/while loop in a modern imperative language code 
should *necessarily* involve a side-effect or it is coded wrongly. 
Even then it can almost certainly be recast to preserve the side-
effect and remove the loop – unless you are implementing the implicit 
iteration function.

This has nothing to do with tail recursion optimization and all that 
Lambda Calculus stuff, this is to do with correct levels of 
abstraction that allow the tool chain to maximize support for the 

Java programmers are having to come to terms with this. Python 
programmers sort of have, except that BDFL has failed to accept the 
correct end point and still likes loops. Scala has done it all wrong.
