LRU example doesn't work

[fredcallaway]

Forgive me if I'm missing something obvious...

julia> using Memoize, LRUCache

(@v1.4) pkg> status Memoize LRUCache
Status `~/.julia/environments/v1.4/Project.toml`

           println("Running")
           a + b
       end

I guess this package isn't being maintained? For other users, the simple fix is just to wrap the LRU initialization in an anonymous function:

@memoize (() -> LRU{Tuple{Any,Any},Any}(maxsize=2)) function x(a, b)
    println("Running")
    a + b
end

also https://github.com/JuliaCollections/LRUCache.jl/issues/18 the packages don't seem to be actively maintained? @kmsquire ?

I think this was fixed, works for me now:

julia> @memoize LRU{Tuple{Any,Any},Any}(maxsize=2) function x(a, b)
           println("Running")
           a + b
       end
x (generic function with 1 method)

julia> x(1,2)
Running
