I agree with the ambiguity of the break statement. And, although I also
agree that it's easy to simulate a break statement with standard blocks,
I still think it's much easier to stop a loop at once with a break
within the loop block. At least when we are sure of where our break
statement will take us to...

This sound's too much like a goto statement. IMHO, it would be cleaner
if we could label a block and then break out of the block - something
-- finds for the first occurence of an element in a matrix
i = 0
while i < m do
j = 0
while j < n do
if matrix[i][j] == wanted then
j = j + 1
i = i + 1
Dijkstra would like it better, for sure. :-)
