According to n2531, the new C++0x initializer-list is allowed in []. 

Test Case:

#include <map>

void test(void)
{
        std::map<std::pair<int,int>,int> the_map;
        the_map[{0,1}] = 5;
}

Error:
/tmp/test.cc: In function ‘void test()’:
/tmp/test.cc:6: error: expected primary-expression before ‘{’ token
/tmp/test.cc:6: error: expected ‘]’ before ‘{’ token
/tmp/test.cc:6: error: expected ‘;’ before ‘{’ token
/tmp/test.cc:6: error: expected primary-expression before ‘]’ token
/tmp/test.cc:6: error: expected ‘;’ before ‘]’ token

Actually, this one seems invalid to me: std::map does *not* define an
operator[](std::initializer_list<>). Waiting a bit for Jason to confirm, then
closing.

how is this invalid?

it shouldn't matter whether map defines operator[](std::initializer_list<>),
only operator[](std::pair<int,int>) for std::map<std::pair<int,int>,int>.

{1, 2} should then be used to initialize that pair.
