Compiling the folowing using is_iless as the predicate for a multi index container results in errors. When is_less is used instead, it compiles fine.

It's a common misconception, that is_iless is for a string comparison. Its isn't actually. It is designed to compare characters and it is used as as pluging to string processing algorithms, that work on character-by-character basis. And it does not provide unary_function interface, since its operators is template based for convenience. Best Regards, Pavol
