Rationale (November, 2014):

According to 9.3.3 [dcl.ambig.res], T() is to be taken as a function type, so the cast interpretation is correct, and one of the examples in this section is very nearly exactly this case.

The disambiguation of a fragment like

  (T())*x

where T is a type and x is a variable, is unclear. Is it a cast to type T() of the expression *x, or is it a binary operator * multiplying a value-initialized T by x? Current implementations treat it as the former, which is not helpful since the specified type is a function type and thus always ill-formed.
