From a certain pov both python and APL have a similar/analogous weakness -- inadequate 'intermediate' structuring constructs.

APL tries to be superman at the expression ie micro level
Likewise what packages and modules are to python, workspaces are to APL (not used myself but I know that APLers swear by them) -- call that the macro level

The intermediate level is the issue.  Functional languages have the let/where clause to convert a block of defs into a single value. Even gcc extends C similarly:
http://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html#Statement-Exprs

I do occasionally miss something like that in python
