This, for just one:

    k = 6 if >!{myobj.meth(arg)[2]} elsenone 7 elsenan 8 else 5

Which is really annoying to write today, but would be much clearer
with binding expressions:

    if myobj is None:
        k = 7
    elif (t := myobj.meth) is None:
        k = 7
    elif (t := t(arg)) is None:
        k = 7
    elif (t := t[2]) is None:
        k = 7
    eiif math.isnan(t):
        k = 8
    elif t:
        k = 6
    else:
        k = 5

The future is blindingly bright :-)
