Getting closer to t-shirt programming.

Annoys me:

  • Assembly hard to read (not sure how to improve it)
  • Counter is incremented at match time, not at eval time
  • No test suite for basic correctness (error reporting not tested for example)
  • Can concat/splice be even shorter?
    • Splice into a list?
  • cd/pwd behavior in compile.sh
  • New frequency analysis after instructions change

Diff from memoizing:

meld ../rlmeta-memoize-failures/vm/ .

* Assemble function in support
* Replace builder with join/indent
* Let compile.sh do error reporting (support only gives information)
* Compact and modify formatting to better suit poster
* Only one semantic action class
