Writing loops over sequences is harder in C++ than in other
languages, many of which provide a dedicated "foreach" looping
construct. In this talk, Eric describes how to implement and use a
generic, type-safe and extensible foreach construct in C++ with the help
of the preprocessor and some sneaky template tricks. The techniques,
first presented in the Nov. C/C++ Users' Journal, are extended to work
with STL containers. Time permitting, Eric will describe why
std::for_each doesn't cut it, and why we need a language extension.
