I forgot to put in my question that I am looking for a macro and not
template if possible, and for a solution as elegant as BOOST_FOREACH,
where you have to code as less as possible. It not (only :) ) that I
am lazy to write, but I think the resulting code would be easier to
read.
furthermore:
1. exception... throwing the exception removes the complexity of
writing but introduces the complexity of exception (writing code +
runtime).
2. pointer... use cases I would like to avoid pointers, as I have
other constraints to work with const references.
Why?  What's wrong with

if(const data_type* data = get_value(map, key)) {
    processResult(*data);
}
