One man's powerful is another's simple
A beginning C programmer treats lists as a "data structure" for an advanced
course on data structures
A beginning python programmer starts using them in his first hour or at worst day

Likewise python does this with the help of numpy

My guess of Marko's intent of bringing up APL is just to show a language in
which numpy is effectively in the language core

My other guess is that these same 9 lines could be translated to R with no import

PS I am not advocating numpybuiltintopython
