I can't see why would your syntax be superior to SpiderMonkey extension
except saving few characters.
Can your syntax support code like this:
async function foo() {
try {
throw new Error();
} catch(e if isNativeException(e)) {
// special handler for DOM exceptions
} catch(e if e instanceof (await
fancyClassLoader.load('classes/SomeLibrary/UserDefinedError'))) {
// load class asynchronously if it wasn't loaded
}
}
?
