[[
throw an exception
]]

Could we clarify that this throws exceptions for invalid arguments
the same as *operations* (not *attributes*), if this is correct?

This came up in asking what happens if you pass an invalid value for
enumeration argument;
a constructor is a method (on the global object), hence presumably the same
behavior as operations (methods on interface objects): throw TypeError on
invalid value.

However, it's potentially ambiguous, as constructors set *attributes*,
and for attributes assigning an invalid value is *ignored*.
