[development] $node namespace woes -- can we fix this in D6?

If you're referring to this in the coding standards:

"Global Variables - If you need to define global variables, their name
should start with a single underscore followed by the module/theme name and
another underscore."

It never occurred to me to interpret this for database columns.  I read an
implied "php" before global variables, thus

global $example; // bad
global $_mymodule_example; // good

I even added a rule to coder to check for this, but had to add exclusions
for a couple dozen core modules that didn't follow this convention.

The standard Moshe is talking about is somewhat implied here at the  
bottom in the naming convention section:


It should probably be explicitly spelled-out though in terms of  
stuffing data into node objects and the like. I think putting it in  
doxygen is critical. I real api.drupal.org 100 times a day. Handbook  
maybe once a week. :)

I (heart) standards.
