shim-array - global prototype modification

[anilanar]

kriskowal/q#551

Although I think naming it Array makes the most sense considering the naming convention used by the library, doesn't it break the modular nature of it by modifying a global prototype?

[kriskowal]

Yes, there is certainly a tension here between one kind of modularity and another. Collections and FRB benefit from having a uniform, generic interface across all collections, so in this case, an array can be used as a Set.
