How much of the training data that LLM's learn from do you think have 
not been properly initialized?

A large percentage of the C test files for ImportC that dates back over 
40 years, is not initialized. There are reads on unitialized variables 
EVERYWHERE.

As for modern editors, the best case scenario is that they run a static 
analyzer to catch such cases. So for D, don't expect that to happen.

Not even Walter uses an IDE. He has his own.
