Currently, dynamic `import()` throws the following SyntaxError when
used without a specifier:
> import();
< Uncaught SyntaxError: Unexpected token )
From the error message, it seems this the result of the code snippet
being seen as static `import` followed by parens, as opposed to
`import()` with no specifier.
This patch makes this error message more clear:
> import();
< SyntaxError: import() requires a specifier
