Using $1 which results from your capturing parentheses in addition with split seems weird. Imagine, you're excluding the chunks specified by the pattern from the resulting list and capturing the values which match the pattern (\".*?\"(?=,))|(.*?(?=,))|(.*?(?=\n)) itself.

The lookaheads are okay though.
