It's not valid.  See ARM 5.19:

 "A constant-expression can involve only literals, enumerators,
 const values of integral types initialized with constant expressions,
 and sizeof expresions."

The expression `object.x' involves the sub-expression `object', and
`object' is not a "const value of integral type".

In case there should be any lingering doubt, ARM 5.19 states quite
explicitly that "class objects ... cannot be used".
