It's not just implicit conversions. It's misuse of operators, too. Using the '+' operator string append is the kind of thing that language designers get initially seduced by ("it just makes sense" "so convenient" "neat") but the reality is that combined with implicit type coercions it's just a recipe for exotic and unexpected behaviours. Precedence rules and expectations for 'string append' vs 'add numbers' is different. And then if you through in 'multiplication = repeat.' It's ... now you have this Wat-talk video (which is a classic which I always share with people when the topic of this comes up.) Maybe I'm just getting stuffy as I get old, but the older I get the more .. explicit.. I want my PL semantics to be.
