Hi,

I propose to add a simple helper function to create an iterator range of boost::transform_iterators. This would effectively create a view over a different range or a container.

Currently this is possible to do with considerable code duplication:

make_iterator_range( make_transform_iterator(vec.begin(), fun), make_transform_iterator(vec.end(), fun));

Here "fun" could be a rather complex lambda or bind expression. What I propose is to wrap these calls into a simple generator make_view. The above code would look much better:

make_view(vec.begin(), vec.end(), fun);

or

make_view(vec, fun);

I've attached a sample implementation of the make_view function. Do you think this could be useful?

I want this utility on a regular basis.

I like this too. Should this be in put in Boost.Range? Or should this be a Utility? -- Dean Michael C. Berris Software Engineer, Friendster, Inc. [http://blog.cplusplus-soup.com] [mikhailberis@gmail.com] [+63 928 7291459] [+1 408 4049523]
