it seems that Method#inspect does some magic with alias methods

code:
(({class A
def xyz
end
alias ver xyz
end

p A.instance_method(:ver) #<UnboundMethod: A#xyz>
p A.instance_method(:ver).name #:ver

a=A.new
p a.method(:ver) #<Method: A#xyz>
p a.method(:ver).name #:ver
}))

shouldn't the #inspect method use the #name one?

maybe #alias? and #alias_target and maybe inspect return something like 
#<Method: A#ver(xyz)> so it can be seen that the method is an alias?


PS: sorry i cant get the code tag working currectly

shouldn't the #(({inspect})) method use the #(({name})) one?

maybe #(({alias?})) and #(({alias_target})) and maybe (({inspect})) 
return something like ((%#<Method: A#ver(xyz)>%)) so it can be seen that 
the method is an alias?

Target version set to next minor

Nobu, you add new method Method#original_name on r39223.

Could you explain about it, why and what?

I make the target version of this ticket `next minor'.
If it should be applied to 2.0.0, please change it and make backport 
ticket.

To obtain original method name, when the name is an alias.

No, I don't think it needs to be backported.
