 Synopsis: variable name treated as function pointer

 State-Changed-Why:
     There is an ambiguity in the grammer see 8.2/1 in the
     standard. Here C++ treats Integral n(Integral ())
     as the declaration of a function called n which returns
     an Integral and takes as a parameter `Integral ()', which
     itself is taken as an unnamed parameter of function type
     returning Integral and taking no parameters. That silently
     decays to a pointer to said function. Hence the diagnostics
     given.
