capturing (or not) mutable local variables

So, I just recorded a small video about unit testing in which I used a
lambda find an empty space on a tic tac toe board.

The point is, the board was final, but not immutable.  Most of this
discussion could be reduced to:

final = immutable = safe for multithreads

but the simple fact is

final != immutable

and most of this discussion has been badly founded.
