repl

What steps will reproduce the bug?

Try in the repl:

> let packageJSON = await import("./package.json", { assert: { type: "json" } })

Uncaught SyntaxError: 
let packageJSON = await import("./package.json", { assert: { type: "json" } })
                                               ^

Unexpected token ','

How often does it reproduce? Is there a required condition?

This happens consistently, curiously the features seem to work separately but not together:

// Both of these are fine:
> let p = import("./package.json", { assert: { type: "json" } });
> let p = await import("./package.json"); // Runtime error due to missing second arg

What is the expected behavior? Why is that the expected behavior?

This should parse as it is perfectly valid syntax (and it works without await).

What do you see instead?

The error:

Uncaught SyntaxError: 
let packageJSON = await import("./package.json", { assert: { type: "json" } })
                                               ^

Unexpected token ','

Additional information

There was recently changes to the import assertions proposal to change assert to with (along with changes to affect runtime), but even with that the parsing of the above would be the same anyway.
