Incorrect dev warning with export function named() {}

[rixo]

Describe the bug

In dev mode, when a component exports a named function with the function keyword, then a warning "created without expected prop XXX" is issued in the browser console.

Example:

<script>
  export function propOrNot() {}
</script>

Logs

WARNING <Child> was created without expected prop 'propOrNot'

To Reproduce

REPL

Expected behavior

No warning.

Severity

To me, zero... But I guess the fix is probably trivial. And maybe the incorrect state that leads to the warning might also be a cause for more annoying bugs?
