GLS - Generic Little (Object, Type, Anything, ...) System

It provides multiple dispatch for Racket.

Differences from Swindle:

• Doesn't force you to change all. GLS is a small collection with a dozen of functions in API. It only adds generic functions.

• It based upon types, not classes. You may dispatch you function on any predicate you may imagine: exact-integer?, (real-in 0 10), (and? stream? (not/c stream-empty?)), ...

GLS is based on Greg Sullivan's <a href="https://github.com/gregsgit/glos">GLOS</a>, that was witten for scheme48. It has the same API, but without implemetation of own object system (glos-records). So GLS is not "generic little object system", but simply "generic little system". But I added support for racket/class: you may use class instead of type predicate and GLS correctly supports subtypes (subclasses).

Sorry for bad documentation: for API look into <a href=https://github.com/Kalimehtar/gls/blob/master/gls/main.rkt> main.rkt</a>, for examples of use -- <a href=https://github.com/Kalimehtar/gls/blob/master/gls/test.rkt>test.rkt</a>.

Some description of GLOS is in the paper <a href="https://github.com/gregsgit/glos/blob/master/ref-dyn-patterns.pdf">ref-dyn-patterns</a>.

Also, slides in <a href="https://github.com/gregsgit/glos/blob/master/proglangsandsofteng.pdf">proglangsandsofteng</a> work through some examples using GLOS.
