capture() turns "yourself" into a tasklet.
Suppose you have a tasklet, running function f() and
you want to remove it, you can accomplish that with a function g()
which turns itself into a tasklet and captures its caller:

def f():
    ... do stuff
    g()     # this will do the capture()

def g():
    temp = tasklet().capture()
    # note that this one is removed already

BTW., this info is available via the doctrings.
I suggest to look at all of them, it is the only
documentation at the moment.

Another question: Why do you actually *want* to remove the
current tasklet? I consider it suspicious, if not an error,
when people think they want to do this.
