4c0f716aef Change the representation of SolverState to have a "saved environment", recognize the "Save the Environment" variable 2013-07-19 17:50:16 +02:00

807076ad57 Add CSaveEnv, optimize CAnd, make it prettier 
CSaveEnv is a special constraint that indicates that the current
environment should be saved for later use.

(/\) now optimizes away arguments that are already CTrue.

fceb46dd4e Try to support polymorphic pattern matching 
Expands each pattern into basic PVars to attempt to recover polymorphis
through the same mechanism. Need to test further.

8145e600fc Create MetadataModule for more refined information about modules 
Used in most places to break a module into more orthogonal components.
Some of this data needs to be serialized into the interface files.

67ef1ec77b Create the Type.Inference module which handles type inference from 
start to finish. Give it a Module and it returns a dictionary mapping
top-level values to types.

18adffc06d Turn unary negation back on. 2013-07-16 00:36:34 +02:00
Evan Czaplicki
90d50dbb13 Turn off unary negation parsing for now. It has weird behavior when 
paired with function calls:

  (- sqrt 9)   -- parse error
  (-sqrt 9)    -- type error, cannot negate function
  -(sqrt 9)    -- this works
  - (sqrt 9)   -- parse error
  - sqrt 9     -- parse error

1fcb01f743 Finish switching over to '_Tuple' format for tuples. 2013-07-15 01:05:14 +02:00
Evan Czaplicki
0070a844d0 Switch the internal data constructor name for tuples. Before tuple 
constructors could be shadowed by user defined ADT's such as "Tuple0",
"Tuple2", etc. Now it uses "_Tuple0" to make it impossible to overlap
with user defined ASTs.

Evan Czaplicki
343dcf2250 Add support for unary negation with the '-' symbol. Makes the use of 
'-' whitespace sensitive, as in the unary negation proposal in
elm-discuss.

f -1  == f (0-1)
x - 1 == (x-1)
x-1   == (x-1)
