Subject: Re: trouble understanding const_set()

OK, I guess I understand const_set... I guess I even understand the scoping
rules, but I certainly don't *get* the scoping rules.

:)

Even though self is Bar, we are at Foo scope?  I'm sure there's some sort of
good reason for this, but could someone clue me in?  I'd be far less likely
to get "had" in the future if I understood the principle behind the
behavior.

Thanks,

Chris

This has little to do with const_set - its essentially a
consequenz of general ``constant'' scoping rules .

---
class Foo
  def Foo.foo
    const_set 'Constant', 'just a string'
    puts self.inspect
    puts Constant
  end
  Constant = 'surprise'
end

$a = Object.new

class Bar < Foo
  def $a.show
    puts Constant
  end

end

Bar.foo
$a.show
---
Bar
surprise
just a string
