I can see what you're trying to say and it would be truly flexible if
you could do that.
But I can already foresee the reaction from the die-hards, and that is
that it would give the person doing the markup "too" much power.
Probably get at some things that shouldn't be gotten at, like MyBean.wait().
Nice idea, wouldn't get past the committing committee I'm afraid.
And the fact is, if you want to get that sort of power, you may as well
script it. There's plenty of ways to get a hold of your object for
scripting. The MVC model is to decouple a the model. Having access to a
specific api isn't decoupling.
