Thank you!

I found another corner case.  The following code should be prohibited in a wrapped script:

```
MAIN = self

module X
  MAIN.send(:using, Module.new)
end
```

I suggested changes in the following comment:

I noticed that this file works when loaded with `load`, but fails if you pass `true` (or a module) as the `wrap` argument.

```ruby
# using.rb
using Module.new
```

This works:

```ruby
load "./using.rb"
```

This doesn't:
```ruby
load "./using.rb", true
# raises RuntimeError (main.using is permitted only at toplevel)
```

I believe the latter should work.
