Rather than having it on a function-by-function basis, meaning different APIs would have different rules, I am warming to the idea of having a per-file strict mode. That is, if you used something like “use strict;” at the top of your code, functions you called would have strict parameter type checking. But if you didn’t, they’d be loose. This way all APIs would be consistent, but you’d have the choice of strictness or non-strictness as you see fit. This would be similar to Hack’s Strict and Decl modes. I’m not necessarily saying it’s the best idea, but it’s certainly an option. The syntax is already reserved! ;) Thanks. -- Andrea Faulds http://ajf.me/
