continue loop without iteration...

[kasper37 at caffeinedreams.com]

basically, this is what I need to do:

x=1
y=x

while x <= y:
    if something:
        x=x+1
        y=y+1
        continue
    dosomething
    x=x+1

therefore, if the if statement is always true, it should never end,
but as soon as it's false, dosomething will happen and it will stop.
