If I understand the docs correctly, POSIX automatically exports pretty much everything except for subroutine names that conflict with Perl built-ins. If you wish to protect your namespace, the easiest way to override this unfortunate behavior is to invoke POSIX like this: 

use POSIX (); # Import nothing.

print POSIX::pow( 2, 3 ); # Use the fully-qualified name.
