That's a good point. It might make sense to avoid enforcing lazy parsing
for
arrow functions with simple parameters. I expect arrow IIFE to become a
not
too-uncommon use case.
What's the right way to get ahold of this information in the PreParser? I
don't
have a real FunctionLiteral, so there's no Scope to check
has_simple_parameters() on.
