* Ruby sequence <-> C++ container wrapper
|

|
|
*
|

|
|
* This wrapper, and its iterator, allows a general use (and reuse) of
|
||
|
|
* the the mapping between C++ and Ruby, thanks to the C++
|
||
|
|
* templates.
|
||
|
|
*
|
||
|
|
* Of course, it needs the C++ compiler to support templates, but
|
||
|
|
* since we will use this wrapper with the STL containers, that should
|
||
|
|
* be the case.
