//: as this will be associated with both namespace 'bsl' and native

//: test scenario is implemented in the test driver of the
//: 'bslim_bslstandardheadertest' component to avoid include loop.
//:
//: 2 Explicitly introduce both namespaces ('bsl' and 'native_std') and
//: call all 10 range functions for an array of integers. (C-1)
//
// Testing
// CONCERN: Range functions are not ambiguous with 'std' under ADL
