subset NonNegativeInt of Int where * >= 0;
proto fib (|) is cached returns NonNegativeInt {*}
multi fib (0) { 0 }
multi fib (1) { 1 }
multi fib (NonNegativeInt $n) { fib($n - 1) + fib($n - 2) }
say fib(100)

muraiki / my functional things
Created Sep 21, 2013
A concussion has prevented me from doing much coding these past 9 months, but in a fit of boredom I wrote this...
View my functional things
lazy semantics and lambda abstractions
point-free in style and pure computation
memoization gives simple caching
these are a few of my functional things
when the state bites
when the C stings
when impure is bad
I simply remember my functional things
and then I don't feel so mad
