Hey, I'm wondering what the community thinks about this... I feel that if I have modules/foo/foo.module checked into drupal.org CVS and drupal.org/project/foo, then this module stakes a claim to the foo_... namespace. That is, I can name my functions foo_whatever without worrying that some other module out there already defines the same function. Similarly, I can name my variables foo_whatever, database tables, and so on. Now, let's say someone else checks in a module called foo_bar. And say both modules define the same function, variable or other namespace collision. What then? Is that a bug, and if so which module is responsible for fixing it? If you want a concrete example, both fb.module and fb_social.module define variables starting with "fb_", and specifically I wonder how to respond to http://drupal.org/node/943462. I don't want to start a flame war. I'm curious if there is community consensus or official policy. Personally I think its a bad idea to name any module with an underscore. That is, drupal.org/project/foo_bar should instead be drupal.org/project/foobar, as this avoids any confusion. -Dave
