+ + Chg : INCOMPATIBLE CHANGE: The level is now absolute and no longer
+ relative to the current frame - we'll call it "context" from now
+ on. You should replace all your raw levels by combinations of
+ words.
+ The old behaviour of "=> $n" can be easily reobtained by using
+ "=> SCOPE($n)".
+ + Fix : As a result of this change, the module now plays nicely with
+ the debugger.

+ + Fix : Stack mess when using unwind() in scalar context.
+ + Fix : Returning an automatic variable isn't wise, so let's use a
+ context instead.
+ + Doc : Clarifications.
+ + Tst : Stress tests for unwind().

+ Add : unwind(@things, $level), that returns to an upper context.
+ Add : want_at($level), that gives the wantarray for $level.
