＠memoize macro for Julia

Memoize.jl

Easy memoization for Julia.

Usage

@memoize function x(a)
	println("Running")
	a

julia> x(1)
Running

julia> x(1)

By default, Memoize.jl uses an ObjectIdDict as a cache, but it's also possible to specify the type of the cache. If you want to cache vectors based on the values they contain, you probably want this:

using Memoize
@memoize Dict function x(a)
	println("Running")
	a
end
