Why not start at break 0 not break 1, similar to sequences starting at index 0?
Maybe if break alone without integer, it breaks from the loop it is at similar
to the behavior we have right now in Python.
E.g.,
for matrix in matrix_array : # Index 0
for x in range(0,10) : # Index 1
for y in range(0,10) : # Index 2
for z in range(0,10) : # Index 3
if matrix[x][y][z] == 0 :
print("Found !")
continue 3 # which is equivalent to continue/break alone
