[Grace-core] Fwd: Some notes on pattern matching on the wiki

> Others may have different desiderata for modules.  I think that we will reach closure on this faster if we first talk about what they are /for/.  If our purposes can't be accomplished with objects, then we should certainly invent something else.  Otherwise: concepts "should not be multiplied beyond necessity"!


So my #1 purpose for modules is: to support teaching about modular programming :-)

my #2 purpose is to support "language levels" via configurable libraries. 

I'm not sure if I'm using a "smallest - highest priority" or "largest-highest priority" ranking system.
