Hi Gael,

nice job, I'm sure many users will be very happy to see this project.

Thanks :)

meaning the overhead of such a wrapper is largely dominated by calls to operator new. So maybe the conclusions of that could be: - is there a way to reduce such heap allocations ? and if not: - for the user prefer "inplace" operators whenever it is possible - functions like add(a,b,r) doing r = a+b would be ugly but much faster than r = a+b, well, unless there is a way in python to map r = a+b to add(a,b,r) ? - I'm only nitpicking ? ;)

Thanks for the input in any case, it's appreciated! -Jussi
