I'm migrating my codebase to 10.1 and I have functions called async (some external, some let) that were defined long before ReScript considered adding async/await.

Is this supposed to be allowed now that async is a keyword? Simple functions work, but functions with named arguments throw a syntax error after the function call such as Did you forget a => here? when I attempt to call them:

let async = (~a, b) => a+b let _ = async(~a=1, 1) 

I'm happy to say redefining async shouldn't be allowed, but then let async and external async should trigger an error rather than at the call site.
