[issue35515] Matrix operator star creates a false matrix

[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

[[0,0]]*4 is not a matrix definition. You are defining a list that shares the same list object four times. It's a common misunderstanding how list works, see https://stackoverflow.com/questions/240178/list-of-lists-changes-reflected-across-sublists-unexpectedly
