I ran this under cfront 2.1.  Note the error it gives:

CC mi.C
AT&T C++ Compiling System, v2.1
CC  mi.C:
"mi.C", line 17: error: no standard conversion of  E (*)() to  B *
1 error

"E myObject();" is the declaration of a function; "E myObject;" would be
the declaration of an object variable, initialized by a parameterless
constructor (which, by the way, compiles fine)!
