And if this were merely syntactic sugar, then it would seem unnecessary.
However, the ability to change the semantics if the ":=" operator in
existing code is a powerful one, comparable to the ability to change
what was an attribute access into a function call.
If this were available, perhaps it would be used more often than the
"set_attribute" functions currently are?
