thank you very much ! great !

I can't get used to this late 'if' syntax !

@Gerard
nice hypercube function. But I'll keep with my implementation :
I like to believe that the less the 'debug pointer' stands in the
python code, the fastest the code is (or is potentially)

I keep thinking that
def hypercube(ndims) :
    for i in range(1<<ndims):
        yield [i&mask==mask for mask in [1<<j for j in range(ndims)] ]

but thanks for you proposition, it's interesting anyway
