It's not same, but it's same, look:

for( ... ) {
	while( ... ) {
		if(cond) goto exit;
	}
}
exit:

is equivalent with:

exit:
for( ... ) {
	while( ... ) {
		if(cond) break exit;
	}
}

or

for( ... ) {
	while( ... ) {
		if(cond) break 2;
	}
}

goto <label>:
- we can jump into another loop, not so good

break/continue <label>
- little confusing syntax: break terminate executing labeled statement
and transfer control to the next statement.

I don't need 'goto' but I prefer to extend break/continue. Always if
possible to set a flag in loop and use it to escape...  :)

goto can help, but mostly create unreadable code...
