Granted, it would be nice to have fast for loops (for those times
where you really just have to use one). However, I do also enjoy the
challenge of having to come up with fun new ways to avoid them.
There's nothing more satisfying than taking a couple lines of code
wrapped inside a for loop and turning it into one line of convoluted
array operations. Normally I have no artistic talen what-so-ever, so
coming up with confusing idl code in order to avoid for loops is my
way of expressing my creative talents :)
