Note that this unobservable mutation occurs before the function object is 
available to script.

Because UnaryExpression may evaluate to a reference to an existing object, in 
which the mutation of 'constructor' from not-own to defined is observable,

Mutation of operator operands apart from ++, +=, 'delete' and the like is a bad 
idea. Some object to .{ on this basis. 'class' unary prefix would be even more 
unusual.
