Wow, nearly perfect timing for me - lot of csv to parse, and transform into their final destination (mostly map with correctly asserted/cast value - some with instaparse, joy of badly separated data). So, cast-with is very appreciated !
Seem to cover everything - even lazy loading so... what's not to like ?
