Re^7: poll ideas quest 2021

I think the problem with -bar is that it is difficult to disambiguate between the expression '-' bareword and '-bareword' as a single token. Maybe you can fix that by post-processing the generated tree, but my impression is that Sawyer wanted to avoid any "special" logic and have a purely EBNF-driven approach.

I think the problem with `-bar` is that it is difficult to disambiguate between the expression `'-' bareword` and `'-bareword'` as a single token. Hmmm... you mean like `-bareword` and `-function_call`? Since standard requires parens on function calls, which is something I understand is probably going to be necessary for parseability, wouldn't that disambiguate the two? Or do you have another counterexample in mind?	[reply] [d/l] [select]
