greg f158b6c712 Converted to multiple-evaluator logic 
Now I have (basically) full single-step evaluation and it works fine

+  make operator evaluation more concise

greg 84fbe73cf6 Add Lambda type 
And change name FuncNode -> FuncDefNode

Now function definition nodes reduce to a Lambda, which is not
reducible.

In the hopes of making it shorter
 2017-09-19 22:10:58 -07:00
greg 9b62efc830 Fix conditional parsing 
Needed to account for semicolons/newlines. Maybe need to generalize
delimiter-separated list of things
 2017-09-19 22:10:58 -07:00
greg f626ca1427 Add test for conditional parsing 2017-09-19 22:10:57 -07:00

Not to eval yet
 2017-09-19 22:10:57 -07:00
greg 9cc9c5977d Fixed evaluation of function calls 
This bit still isn't quite small-step but maybe that's okay for
functions

greg ed9d1312d1 Change representation of variables 2017-09-19 22:10:57 -07:00
greg 29d9e50311 All environment changes represented explicitly 
Start the work of rewriting the evluator to be a true small-step
evaluator - that is, all state changes are represented explicitly as
SideEffect types, and not as methods called on the evaluator, except at
the very top of the evaluation loop
