[REBOL] Re: Objects, Inheritance and Barking Up Wrong Trees?
From: scott:dunlop:nextel at: 27-Apr-2001 0:22
My latest guess, found after digging around in the mailing lists and looking
at information on how to create private object slots, is to use 'uses' to
declare a local variable to hold the old value..
child-object: make parent-object [
uses [old-somefn] [
old-somefn: get 'somefn
somefn: func [ .. ][
.. old-somefn ..
]
]
]
It appears a lot less brittle, since old-somefn is now local to
child-object, and objects derived from child-object can use the same
pattern. Does anyone know of a special case that would break this? (Beyond
redefining 'uses' in a parent.. )
