Possibly this could/should be a warning in the IDE as it can cause a bug that can be hard to spot.
For example we have this code:
This will give an error:
java.lang.RuntimeException: Object should first be initialized (List).
In this simple example the coding mistake will be easy to spot, but with more complex code it can be tricky.
Also, I think it makes no sense ever to code like this as the provided argument can never do anything useful.
So, maybe there should be warning about this in the IDE.

For example we have this code:
B4X:
Sub AddToListItems(lst As List, iAdd As Int) As List
Dim i As Int
Dim lst As List
For i = 0 To lst.Size - 1
lst.Set(i, lst.Get(i) + iAdd)
Next
Return lst
End SubThis will give an error:
java.lang.RuntimeException: Object should first be initialized (List).
