Warning: discarding old <methodName>?

Hmm sounds quite like I thought but I donot see the point.

May it come indirectly through require statements like:

  • module M requires a.rb and b.rb
  • both, a and b require c.rb

I’ll have to examine tomorrow, for today it’s enough :wink:

I use stable 1.6.7 on win32

Best wishes

Hi folks,

why does this warning come up?
What might be wrong with my code?

The warning (“discarding old ”) comes up when you discard an
old method :slight_smile:

It basically means that you’ve overridden a method without saving
a path to the old version of the method.

For example:

class String
def split; end
end

However, if you do this:

class String
alias :oldsplit :split
def split; end
end

the old method is still available (as oldsplit), so it has not
been discarded and there’s no warning.
