Re: [ceylon-users] Accessing function/method parameter via metamodel => index/name

[Gavin King]

Hi, no, this is not currently possible. The rule is that you're only
allowed to reference things that are in scope. 'someMethod()' is in
scope because it's shared. But 'one' is not.

I agree that this is a restriction we should probably relax. I'm not
sure if we already have an issue for that.

Yes, that's right.
