That's a different kind of thing. "the mouse" is a state, not a
control. As a state it can have one of two current conditions. By
asking what the mouse "is" you are querying its current condition, but
by asking the same thing of a control (a button, etc) you are not
explicitly asking for the state of one of its properties, but rather
querying the control object itself:

if button "Quiet" -- references an object
if the mouse      -- references the mouse state

mapping the checked/unchecked state of a checkbox button onto the
object reference requires a whole new level of metaprogramming and
parser inference.
