Warning: discarding old <methodName>?

Hi folks,

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

It comes up on the line where the respective methods are defined.

Thanx a lot,

Hi –

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.
