It's there because in C/C++ one often winds up writing:
(unsigned)x >> i;
to ensure that one gets an unsigned right shift. The problem is that the
cast can have many other side effects if x is not of type int. For
example, if x is a struct with an overloaded cast operator. Or if x is a
long and you just lost half your value.

No.
