[REBOL] Re: Executable code blocks as arguments

From: larry:ecotope at: 22-Aug-2001 10:46

Hi Tim

The code block you pass in has to be bound to the objects context. Change
your modify function like this:

REBOL []
o: make object![
a: 1 b: 2 c: 3
modify: func[arg[block!]][do bind arg 'self]
]

>> o/modify [a: "one" b: "two" c: "three"]
== "three"
>> probe o

make object! [
    a: "one"
    b: "two"
    c: "three"
    modify: func [arg [block!]][do bind arg 'self]
]
