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:

I do occasionally miss something like that in python
