Simplicity is one of Java's overriding design goals.


We believe that every being is divine, is God. Every soul is a sun covered over with clouds of ignorance; the difference between soul and soul is owing to the difference in density of these layers of clouds. - Swami Vivekananda

yeah! right!

try
2**2**2**2**2
on Ruby 15 minutes.

OR

file = File.open("ordinal")
while file.gets
print if ($. == 1) || /eig/ .. ($. == 3) || /nin/
end

No, it can be made scripty. It's really all up to the programmer.

I guess "SCRIPTY" in this case means "doesn't protect you from writing bad code". You *can* do things in Ruby that Java simply won't allow; sometimes, this is good, and sometimes not. I like the freedom I get in Ruby to do great things, while simultaneously running the risk of shooting myself in the foot. Your mileage may vary. ;-)

By the way, I just tried your example. I opened irb, and typed:

> 2**2**2**2**2

in just under a quarter of a second, I got this result:
