To be completely clear, what I want is the ability to choose a frame in the stack backtrace and restart it or return a value from it. In any case, this implies that the computation must proceed either by retrying the call in the current frame or by returning a value from the current frame as if the call in the frame completed with that value, thus overwriting or flushing the frames above the current frame. Note that this is orthogonal to the usual restarts that are established via restart-case and derived forms. IMHO, this feature is absolutely essential in any interactive programming environment for Common Lisp. Can anyone provide me with more information regarding this issue? What was the intended meaning for the unimplemented DEBUG:DEBUG-RETURN? Is anyone porting the stack exhaustion detection mechanism already present in SBCL? Thanks in advance, Ant�nio Leit�o.
