I thought about something like auto fixQuotes(string text) { if (text.canFind("\"\"")) { // some magic } return text; } but obviously, it won't compiled
Something along the lines of:
.byLine.map!(a => a.fixQuotes).joiner("\n").csvReader!...
Either way, you're using ranges!
Its even the same amount of code, if not less.
