Add aplwiki_simple_examples test covering all 30 examples from
aplwiki.com/wiki/Simple_examples. 16 examples are actively tested,
14 are commented out with reasons (missing ⌿, ∈, array indexing
for reading, dyadic trains, ⎕←).
Also fixes two bugs discovered by the examples:
- Reduce now works along last axis for higher-rank arrays
(+/ on a matrix reduces each row, not the whole array)
- 1-element arrays now broadcast like scalars in dyadic ops
(',' ≠ 'text' now works correctly)
- Add ⌿ (reduce first axis) and ⍀ (scan first axis) - Add ∈ (membership): A∈B returns 1 where elements of A appear in B - Add A[i] array indexing for reading (1-based) - Add dyadic train support: ⍺(f g h)⍵ and ⍺(f g)⍵ - Add ⊆ ⌷ ∊ to train function-reference recognition - Allow grammar shift/reduce conflicts (error_on_conflicts false) - Uncomment all feasible APL Wiki examples (10 newly enabled)
