+ + Fix : uplevel() will now use the correct pad when executing its callback. This fixes at least two issues :
+ - closures defined inside the uplevel callback can now correctly
+ access lexicals from inside and outside the callback.
+ - state variables in the uplevel callback now work properly.
+ + Fix : It is now generally possible to call goto() in the uplevel'd
+ code to replace the uplevel stack frame. There are two cases
+ for which it is still not possible :
+ - if -D flags were set when running perl (as in "perl -Dt ...").
+ - if the perl runloop has been replaced with a custom one by
+ another module.
+ If uplevel() detects that the replacement code contains a goto
+ statement, and is in one of those two cases, then it will refuse
+ to execute the callback and throw an exception.
+ Note that this fix implies a run-time overhead of uplevel()
+ proportional to the size of the the callback in every case
+ (with a small ratio), and proportional to the size of ALL the
+ code executed as the result of the uplevel call (including
+ subroutine calls inside the callback) when a goto statement is
+ found in the uplevel callback.
+ + Fix : uplevel() has been taught how to handle XS callbacks properly.
+ + Fix : The cause of "Attempt to free unreferenced scalar" warnings
+ when using uplevel() has been addressed.
+ + Fix : [RT #71212] : build failure on Windows.
+ The module does no longer rely on calling Perl_cv_clone, which
+ isn't exported.
+ Thanks C.H. Kang for reporting.
