Clean up a few items: the 'import os.path as p' syntax and the
'extended-as'-assignment syntax, both of which Guido has decided on.

has to be used to convince the CPython parser it isn't one. For
|
||||
more advanced parsers/tokenizers, however, this should not be a
|
||||
problem.
|

|

A slightly special case exists for importing sub-modules. The
|
||||
statement
|
||||
|
||||
import os.path
|
||||
|
||||
stores the module `os' locally as `os', so that the imported
|
||||
submodule `path' is accessible as `os.path'. As a result,
|
||||
|
||||
To avoid confusion, importing a submodule `as' another module is
|
||||
not allowed. When importing a submodule in the normal way,
|
||||
|
||||
import os.path
|
||||
|
||||
The actual name stored locally is `os', not `path', and the newly
|
||||
imported module can be referenced as `os.path'. When introducing
|
||||
the `as' keyword, it is unclear whether the `os' module or the
|
||||
`path' sub-module should be stored `as' the requested local name.
|
||||
import os.path as p
|
||||
|
||||
should store `os.path', not `os', in `p'. The current
|
||||
implementation does not yet support this.
