Subject: objects as method arguments
Date: Thu, 3 May 2007 01:04:58 +0200 [thread overview]
Message-ID: <20070503010458.778128e2@hmmm.de> (raw)
I want to have the following:
class c = object
inherit base
method m (arg : #base) = arg#do_something
end;;
this gives an error. Is the only way to get this working to write it
that way?
class c = object
inherit base
method m: 'a. (#base as 'a) -> unit = fun arg -> arg#do_something
end;;
If I have more of such methods, that looks rather ugly. Also I
don't want to cast the argument-object to the baseclass type
everytime...
do I overlook something?
cheers
Michael
