Whenever an error occurs in the phpBB Language files, it dies silently. This is understandable..However, it also makes debugging a pain, since it makes it harder to locate the source of the problem.

My question & suggestion is why isn't $user->setup(); and $user->set_lang(); using an internal constant defined check (DEBUG_EXTRA being the constant) to override the @include statement with a normal include statement, and not suppress the include errors? This would help out during debugging for MOD constuction/installation, but not be activated unless the board is in total debug mode anyway.
