Turn off font-locking :-). It wouldn't work.

Is that a convention or there is more to it? They do the same thing,
right?
If you ask me, the fact there are two chunks can be inferred by saying
that they were added as two different calls.

You are cloning a face here?
Are there any workarounds when the value of the text property is a
function or a value type. How can we have clones of a function (or a
symbol)? How can we clone a value type like Integer? May be there is a
way to turn a Value in to a Object? (In C# world, it is called "Boxing")
