[SciPy-User] Does SciPy already supersed NumPy?

[Yuxiang Wang]

I was reading through the link and it mentioned that the first form is
preferred over the second one under most circumstances:

# first form
from scipy import stats
stats.lomax(...)

# second form
from scipy.stats import distributions
distributions.lomax(...)

I honestly think the second form is far more frequently used in the
examples given in the document, for example:

http://docs.scipy.org/doc/scipy/reference/tutorial/special.html
http://docs.scipy.org/doc/scipy/reference/tutorial/integrate.html
http://docs.scipy.org/doc/scipy/reference/tutorial/optimize.html
http://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html
http://docs.scipy.org/doc/scipy/reference/tutorial/fftpack.html

Would you think it'd be better to update this link
http://docs.scipy.org/doc/scipy/reference/api.html#guidelines-for-importing-functions-from-scipy
 ?
