Hi Jinsong,
Not a bug, but certainly something that can be confusing if you don't
expect it. In your example, `helo` is implicitly defined as a toplevel
variable at the point of `set!.
The difference is noted (very, very succinctly) in the manual here:
http://wiki.call-cc.org/man/4/Extensions%20to%20the% 20standard#set
Unfortunately there's not currently a way to generate a warning in this
situation, that I know of.
Cheers,
Evan
