Very slow game of life in a Forth

• Example
• Interpreter

Warning: Slow! (especially in-browser)
More Joy than Forth and buggy

definitions: ~ | instead of : ;
strings: in backticks, disallows | inside
lists: [ ... ] (last cdr is NIL)
pseudo-binding: <string> { ... } binds $<char> for each char in <string>
only NIL is false

words: DUP DUP2 SWAP OVER POP + - * / MOD = < <= NOT ATOM? CONS CAR CDR APPEND RANGE AT PICK REP ZIP MAP LEN FOLD IF EVAL APPLY PEEK POKE SAY SAY; RANDINT WAIT CLS TRACE

some words:

• <cdr> <car> CONS
• <list> <fn> MAP
• <listL> <listR> <fn> ZIP
• <initial value> <reducer> FOLD
• <list> LEN
• <val> <if_not_nil> <if_nil> IF
• <list_of_args> APPLY
• RANGE, AT, PICK, REP are like ↕int, ⊏, ⊑, / in BQN
• ATOMIC is like K, BQN, or APL's pervasion but extremely slow
