Subject: Re: String#de_inspect (and not Kernel#suspicious)

Okay, the block was defined in SAFE mode 0... :)

In the first version, I didn't introduce Kernel#suspicious (see
below). That one worked fine.

Then I naively abstracted the thread thing, which didn't do
what I expected. Oops...

Back to version 1...

Thanks.

       $SAFE = 5

       eval(self, Module.new.module_eval{binding})
     end.value
