'variant' documentation: bug in times_two() example

[dan.tsafrir@…]

This page:

http://www.boost.org/doc/libs/1_38_0/doc/html/variant/tutorial.html

defines the following code snippet:

void times_two( boost::variant< int, std::string > & operand ) {

if ( int* pi = boost::get<int>( &v ) )

*pi *= 2;

else if ( std::string* pstr = boost::get<std::string>( &v ) )

*pstr += *pstr;

}

in which (1) 'v' is not defined and (2) 'operand' is not used. I suspect that this is not intentional, but rather, a mistake. Specifically, it seems that every occurrence of 'v' should be replaced by 'operand'.
