Re: [Python-ideas] Extending expressions using ellipsis

Would this be enforced in the grammar or by the lexer? Since you say you expect the indentation to be enforced, that suggests it would be done by the grammar,

I think it could be done by having the lexer enter a mode where it swallows a newline that is followed by an indentation to a level greater than the starting level of the construct. Then no change would be needed to the grammar. -- Greg
