I used the "raw"-tag to quote the code. Here is it again without the tags:
... So, code like
boost::array<int,2> test; test[2] = 1; test[-1] = 1;
compiles without warnings or erros. Now, adding the following functions to array
template <size_type i> reference at() { BOOST_STATIC_ASSERT( (i < N) ); return elems[i]; }
template <size_type i> const_reference at() const { BOOST_STATIC_ASSERT( (i < N) ); return elems[i]; }
would make it possible to write
boost::array<int,2> test; test.at<2> = 1; test.at<-1> = 1;
which results in the expected error messages.
You can try to use boost::fusion::at_c <N> (test), but not sure if it actually has a static assertion. See

I tried it, but it doesn't static assert. Shouldn't it ? -- View this message in context: http://boost.2283326.n4.nabble.com/array-compile-time-checked-access-tp46381... Sent from the Boost - Dev mailing list archive at Nabble.com.
