Std.App.Cache.lookup
fn
lookup: &Std.App.Cache.Cache[K, V] -> K -> Int -> (Std.App.Cache.Found[V], Std.App.Cache.Cache[K, V])This is a callable function.
What it does
What a lookup found, and the cache that follows it.
The cache comes back because looking something up moves it to the front of
what is kept, and because what was asked for is counted.
