Exceptions

When used with function objects, algorithm calls place the body of the loop away from the call site, which can make the loop harder to read. (Cobbling together simple objects with the standard and nonstandard binders isn't a realistic option.)

[Boost] lambda functions solve these two problems and work reliably on modern compilers, but they don't work on older compilers and they can generate dense error messages when they're coded incorrectly. Calling named functions, including member functions, still requires binder-like syntax.
