3.9.1/7, subnote. 43) says that enum isn't an integral type
but can be promoted to {signed/unsigned} int/long.
an assignment of int to enum produces an error,
so how ( in defined non-hax0r way ) enum can be any integer?
if it can be, then what's difference between enum and int?
$ cat tmp.cpp
typedef enum { foo, bar } e;
e assign( int v__ ) { return v__; }
int promote( e e__ ) { return e__; }
$ x86_64-gnu-linux-g++ tmp.cpp -O2 -c -Wall
tmp.cpp: In function 'e assign(int)':
tmp.cpp:2: error: invalid conversion from 'int' to 'e'
