Tiger.ml
========
A Tiger-compiler implementation in (OCa)ML

Status
------

### Technical issues
- [-] testing framework
  - [x] run arbitrary code snippets
  - [x] check non-failures
  - [x] check expected output
  - [-] check expected exceptions
    - [x] semant stage
    - [ ] generalized expect `Output ('a option) | Exception of (exn -> bool)`
  - [x] run all book test case files 
  - [ ] grid view (cols: lex, pars, semant, etc.; rows: test cases.) 
- [ ] Travis CI

### Features

Implementation Notes
--------------------

### Parser

#### shift/reduce conflicts
##### grouping consecutive declarations
##### lval

### AST

#### print as M-exp

### Machine
Will most-likely compile to RISC and execute using SPIM (as favored by Appel)
