This looks really nice. I'm just a little curious about one little
feature, would this support resizing the buffer? i.e. could I do
def f(int[:] arr):
cdef int i
# ...
arr.append(i)
say? My guess is no but this would be really handy. I sometimes need a
fast resizable container for basic types and find that using a list is
about 4-7 times slower than a simple class exposing a block of memory
with suitable resizing. Creating such a container is easy for one type
but without a templating system this gets too messy when I want support
for ints, longs, floats and doubles.
cheers,
