I vote YES for goto.

If we were voting today if we should remove continue, exit, or retry.
I might say, YES.  Properly created if statments can remove all but,
the exit keyword in for loops.  That can be handled easily with a while
loop and an if statement.

However we are voting to add a keyword that allows very similarly
difficult to track flow of code. If these other easily worked
around ugly keywords are allowed, Then why not a goto that handles
them all?  In fact, in the case of these others keywords.

for index= 1 to x do
  for index2 = 1 to y do
    if v = true then
      continue -- implicit location.
      goto "y_continue" -- explicit location.
    end if
    label "y_continue"
  end for
end for
