sub EXPORT must not use %()

[vrurg]

Documentation of sub EXPORT still uses %() to return exported symbols. This is considered incorrect behavior due to hashes itemizing their values. I.e. instead of, say, exporting a routine a symbol is exported as a Scalar containing a routine.

Correct examples must use Map.new instead of hash:

sub EXPORT {
    Map.new: '&doit' => sub { ... },
        ...
}

Sorry for not producing a PR, don't have time for it.
