[21:38:39] <erg> yo
[21:39:20] <erg> i'm thinking of making all definitions CAPS: .. ; and making the ; optional, except for : .. ;
[21:40:41] <erg> each word knows its own arity. new CAPS: would interrupt the current definition and start a new one. so CONSTANT: CONSTANT: a 1 would make an empty CONSTANT: that would check for two params and throw a parse error
[21:41:12] <erg> then IN: foo works still, and everything looks basically like it did before but you still dont need parsing words
[21:42:31] <erg> CONSTANT: a b c CONSTANT: z 2  would throw a parse error on the first CONSTANT: for having too many args
[21:42:53] <erg> and ; is optional for CAPS: words
[21:43:04] <erg> i dunno

[22:24:17] <evincar> erg: The semicolon provides useful redundancy for error messages.
[22:24:55] <evincar> E.g., "got 2 arguments, expected 1".
[22:30:16] <evincar> How else would you differentiate an extra argument from a regular word call?
[22:33:23] <erg> evincar: all top level code is CAPS:, or else it's an error. so anything before the first CAPS: or between CAPS: ... ; forms is an error
[22:34:44] <evincar> I see.
[22:34:53] <erg> now for CAPS: words, either they end in a ; or get interrupted by another CAPS: form which can't nest. semi case is boring, but if they get interrupted, if they have a fixed arity like CONSTANT: expecting 2 args, then if they get 0,1 arg then file ended or top level form interrupted. if they get 3+ then it's an error on arity check
[22:35:29] <evincar> Sounds reasonable then.
[22:35:55] <erg> and if we hardcode : ... ; as required semicolon, then you dont really lose anything and you dont get ugly code like : 1+ ( a -- b ) 1 + : 2+ ( a -- b ) 2 + ...
[22:36:51] <erg> that's for a module file. for a script file, you can have code wherever i suppose
[22:40:17] <erg> i could even require a semicolon if the definition has 3+ tokens
[22:42:29] <erg> just want the common cases of ``IN: vocab`` and ``CONSTANT: label value`` to work

[23:49:03] <Sonderblade> erg: does that work for tuples? I don't think ; can be optional for TUPLE: ?
[23:53:02] <erg> Sonderblade: i think what has to happen is that nothing knows about arity, just that CAPS: words can interrupt each other. lex everything. then in another pass do the arity rules. any word that doesn't have the right arity throws an error, and if a word doesn't have an arity, then a semi is required
