Loose typing and truthy/falsy values are a disaster waiting to happen, not least b/c it obfuscates intention and also because every language that has it at all

Loose typing and truthy/falsy values are a disaster waiting to happen, not least b/c it obfuscates intention and also because every language that has it at all has slightly different rules. If I had a say I'd want an opt-in for JS that makes it illegal (a runtime error; compilation error for constants) to have anything but a Boolean in the conditional part of an `if` statement.
