No, he's saying that *his hack* using class helper wouldn't cover this case (two objects in the same 'with' clause). Daniel, I find this hack as ingenious as atrocious ;-) But thinking about it a bit, when FPC gets generic methods you can make this kind of workable! > (...) > To summarize, "as" does NOT try to eliminate context ambiguity (also it > won't make a clear context ambiguous), but provided some convenience when > needed. As Sven said this feature has already been requested a few times. I don't remember whether it was permanently vetoed by FPC developers or just is in the to-do, but vaguely remember people arguing it's "un-pascal" because of the local variable/scope - which is unfortunate, because IMO the 'with' syntax is one of the most abominable un-pascal things Borland introduced in the language, and *forcing* the AS syntax (but probably with some other keyword like ALIAS) would make it much more palatable.
