It might be if you were trying to develop an IDE that could syntactically
analyse what the user was typing even if he/she had left a half finished
expression further up in the buffer (I'd kind of assumed this was the
goal). So you're not continuing after errors, exactly, more like
unfinishednesses (or some better word...).
I guess one approach to this would be to divided up the buffer according
to indentation and then parse each block as delimited by the indentation
Two random points:
1) Triple-quoted strings are going to be a problem.
2) Has anyone gotten flex to tokenize Python? I was looking at the manual
yesterday and it didn't look impossible, although a bit tricky.
