Subject: [PATCH] Clone mutables to prevent unexpected issues
|
|
|
|
There are lots of locations in the API where mutable
|
|
types are not cloned, either on return or when passed
|
|
as a parameter and assigned to a field, which can cause
|
|
unexpected behaviors. Let this be a lesson to use
|
|
immutable types for simple things Location, Vector, and
|
|
others.
