I use return for this.
Note that return must be the last instruction of a block, so you have to 
write something like:

print"One"
do return end
print"Two"

Of course, most of the time you do a conditional break, so it would like 
more natural:

print"One"
if condition do return end
print"Two"

Note you can also call os.exit() but it is quite more brutal...
