[drupal-devel] Getting rid of global variables

[Khalid B]

I like the idea in general.

Better change it to be :

drupal_set($key, $value = NULL, $module='system', $force = FALSE)

This way we just have key and value being mandatory. This will be
useful for widespread variables like $user for example.
