Hi all,
when trying to evaluate the following snippet in jolt
(let ((selector 'justTesting))
(add-method object1 'testMethod
(lambda (_closure _self self)
(send 'println: StdOut selector))))
I get an error that "selector is undefined".
Apparently, the problem is that I'm using "selector" in a lambda's body, while
its definition is outside. Indeed, if I just move the (let) inside the lambda
body, it works:
(add-method object1 'testMethod
(lambda (_closure _self self)
(let ((selector 'justTesting))
(send 'println: StdOut selector))))
I'm wondering, though, if I can get things to work the first way? Aren't
lambda's supposed to be closures, so that they can actually access variables
defined in lexical scope? Or is there anything I could do with the _closure
parameter here (what is it for, anyway...)?
Thanks in advance,
Hans
