Exactly. The work-around is much slower (because it has to run the if
statement each iteration), and needs an extra variable.

I think the best and simple enhancement would be to allow this:

for a = 1 to 10 do
    for b = 1 to 10 do
        if b = 5 then 
           exit a --exit the for loop that uses 'a'
        end if
    end for
end for

or for while loops:

while 1 as a do --(as a is optional)
     for b = 1 to length(somevar) do
              if not somevar[b] then
                     exit a
              end if
     end for
end while
