:stepping values are applied _between_ items:

:for 5))
#<range #x86878C6>
CM> (next x t)
(60 59 58 59 60)
CM> (next x t)
(60 59 58 59 60)
CM> (next x t)
(60 61 62 61 60)
CM> (next x t)
(60 59 58 59 60)
CM> (next x t)
(60 59 60 59 60)

rick,
i dont understand the behaviour of 'range' when i write the following:
(setf x (new range :from 60 :stepping (new heap :of '(1 -1 1 -1 1))
:for 6))
as result of
(next x t)
i would expect a list which always contains 61 at the end, but i get
=> (60 61 60 61 60 59)
as well as
=> (60 59 58 59 60 61)
etc.
what is going wrong?
thanks - johannes.
