Constant inexplicably not known (comes up as undefined)

Mon, Oct 8, 2018

Notice: Use of undefined constant CULTURA_YEAR - assumed ‘CULTURA_YEAR’ in CulturaExchangeNode->__construct() (line 105 of /vagrant/web/sites/all/modules/contrib/culturaexchange_migrate/culturaexchange_item.inc).

Other constants also defined in the same file used immediately after this work.

https://api.drupal.org/api/drupal/includes%21module.inc/function/module_load_include/7.x

Oh. The module wasn’t enabled.

But still: why didn’t module_load_include work, or throw a warning?

Oh, it doesn’t work for .module files: https://api.drupal.org/comment/47603#comment-47603
