Summary

  • New variable type: cat box [] (staple reverse-staple) — holds quantum superposition of values
  • New operator: double worm = — the one character INTERCAL has avoided for 50 years, now meaning quantum superposition
  • PLEASE FEED / PLEASE PET statements — identical operations, documented as different, the programmer will never know
  • Hunger counter: starts at 5, dies at 0 (starvation) or 11 (obesity), same error message both ways
  • Cartesian product: mingling two boxes produces all combinations
  • Max 99 superposed values before E2012
  • New gerunds: BOXING, FEEDING, PETTING (for ABSTAIN FROM)
  • --please-peta compiler flag (pending CLI wiring)

Error messages

  • E2007 THE CAT IS DEAD — hunger counter hit 0 or 11 (you'll never know which)
  • E2010 THE CAT IS BOTH DEAD AND A DIFFERENT SIZE — mismatched types in =
  • E2012 THE CAT HAS POOPED IN THE BOX — superposition exceeded 99 values

Sample programs

  • quantum.i — quantum die, rolls 1-6 nondeterministically
  • deadcat.i — demonstrates cat starvation
  • catproduct.i — cartesian product of two boxes via mingle

Test plan

  • 156 unit tests passing (30 new box tests)
  • quantum.i produces random values across runs
  • deadcat.i terminates with E2007
  • catproduct.i produces 4 distinct mingled values from 2 binary boxes

Test specs for the cat box [] variable type: creation, collapse,
grow, merge, cartesian product, hunger counter (death at 0 and 11),
poop limit (99 values), STASH/RETRIEVE with hunger pause, FEED/PET
equivalence, --please-peta flag, and tokenizer tests for [], =,
FEED, PET, BOXING, FEEDING, PETTING.

New variable type [] (staple reverse-staple) holds quantum superposition
of values. The = operator (double worm) creates superpositions. Scalar
assignment collapses the wavefunction. PLEASE FEED / PLEASE PET keep
the cat alive (they are identical; the programmer will never know).

Features:
- Box creation, grow, merge, cartesian product via mingle
- Hunger counter: starts at 5, dies at 0 (starvation) or 11 (obesity)
- STASH/RETRIEVE with hunger pause (suspended animation)
- ABSTAIN FROM BOXING/FEEDING/PETTING gerunds
- --please-peta flag (pending CLI wiring)

Error messages:
- E2007 THE CAT IS DEAD (hunger)
- E2010 THE CAT IS BOTH DEAD AND A DIFFERENT SIZE (type mismatch)
- E2012 THE CAT HAS POOPED IN THE BOX (>99 values)

156 tests passing including 30 new box tests.

Handle DO []3 <- []1 $ []2 in EmitBoxAssignment by detecting
binary ops on two box operands and emitting MingleBoxes.

Sample programs:
- quantum.i: quantum die (1-6)
- deadcat.i: demonstrates cat starvation (E2007)
- catproduct.i: cartesian product of two boxes via mingle

Add comprehensive documentation for the [] (cat box) variable type,
= (double worm) operator, FEED/PET statements, hunger counter,
cartesian products, gerunds, error messages, and quantum die example.

Character naming: [ is "correct horse battery staple",
] is "incorrect horse battery staple".
