Lint for `list += new`

[Mothblocks]

var/list/mob/mobs = list()
mobs += new

This actually translates to mobs += list(), because typed lists aren't real.

OD already throws an error for this.

Is it a separate error code that can be #pragma'd?

[Mothblocks]

It's a side effect from something else, and the error message on it is confusing and unwieldy and should still be considered an issue

That error happens any time you use an inferred new where a type can't be inferred

For example:

var/foo = new()

This isn't quite the same as a lint for the example in the issue, and actually seems to be a bug since it should infer a /list type.
