Detailed Description

Enumerate all elements in iterators recursively.

Enumerate all elements of in an iterable type recursively until the element can be cast to a given VALUE type. The value is than passed into a provided callback function:

enumerate<float>(data, [&](auto& val) { some_vector.push_back(val); });

will enumerate all elements in data, and push them onto 'some_vector'.
