Yes, I lament that there is no way to control how people call your 
function. It can result in surprising things, and it means as a library 
designer you have to consider this usage when picking names.

There are a few "draft" DIP proposals (under the old DIP system) here:

But I think the time of being able to make such a disruptive change has 
passed. For better or worse we have the half-implemented near-useless 
meaning of `@property`, and basically it's unneeded.
