Matchers

comparing: (define $ordering (algebraic-data-matcher {<less> <equal> <greater>}))

compare: (compare 10 10);=><Equal> (compare 11 10);=><Greater> (compare 10 11);=><Less>
compare-c: (compare-c {1 2 3} {1 2 3});=><Equal> (compare-c {1 2 3 4} {1 2 3});=><Greater> (compare-c {1 2 3} {2 3});=><Less>
min: (min {10 20 5 20 30});=>5
min/fn: (min/fn compare {10 20 5 20 30});=>5
max: (max {10 20 5 20 30});=>30
max/fn: (max/fn compare {10 20 5 20 30});=>30
min-and-max: (min-and-max {10 20 5 20 30});=>[5 30]
min-and-max/fn: (min-and-max/fn compare {10 20 5 20 30});=>[5 30]
sort: (sort {10 20 5 20 30});=>{5 10 20 20 30}
sort/fn: (sort/fn compare {10 20 5 20 30});=>{5 10 20 20 30}
sort-strings: (sort-strings {"Egison" "Haskell" "Clojure"});=>{"Clojure" "Egison" "Haskell"}
merge: (merge {3 4 6} {1 2 5});=>{1 2 3 4 5 6}
