pointed out, there's unfortunately no way to constrain the value assigned in anyway, neither before nor after the assignment. That renders the attribute nearly useless as far as I'm concerned.. a pity, since it'd be a lovely way to offer a bit of syntactical sugar. You could even support both the ->bar("baz")
and the ->bar = "baz"
style at the same time, but that's a moot consideration as is. :(
