How to use std::foreach with parameters/modification

Question

I\'ve found myself writing

for(int i=0;iDoWhatever(param);

a lot, and I\'d like to compress this into

If you are using GCC you can define something like:

#define foreach(element, array) \
    for(typeof((array).begin()) element = (array).begin(), __end_##element = (array).end();\
        element != __end_##element;\
        ++element)

and use it after like this:

foreach(element, array){
    element->DoSomething(); //or (*element)->DoSomething() if type is already a pointer
}

I use this on a custom array but it works fine with std::vector too.
