Re: [boost] [iterators] Proof-of-concept for a sentinel iteratoradapter

Giovanni Piero Deretta: ...

for( int i = 0; i < N; ++i ) { m1 += test_strlen( "This is a test." ); }

Are you sure the compiler is not computing the len at compile time?

Good point. Yes, it actually was computing it at compile time. When I changed the test to use a literal in another TU, the sentinel iterator was indeed more efficient: 953 (3577225856); 703 (3577225856)
