In Ruby it's the other way around: 1 is truthy and the block will execute. Everything in Ruby is truthy other than the null reference and Boolean false.
I can understand forbidding non-Boolean values in Boolean contexts - it's not something I'd want myself but I think I get why a reasonable person might. Dart's semantics, though, are really strange: they follow no precedent I'm aware of, and don't seem to offer anything useful in themselves. Does anyone else have some insight here?
- spooneybarger 15y agodart's boolean context semantics are like taking smalltalk's strongly typed ones and putting them through something.. i don't know what they were thinking. the basic idea is sound ( the smalltalk part ) but what they then did around the 'edges' is just downright off.
