NAME

       End - generalized END {}.

SYNOPSIS

           use End;

           {  my $foo = end {print "Leaving the block\n"};
              ...
              last;    # prints "Leaving the block\n".
              ...
           }

DESCRIPTION

       The module "End" exports a single subroutine "end", which allows you to set up some code
       that is run whenever the current block is exited, regardless whether that is due to a
       "return", "next", "last", "redo", "exit", "die", "goto" or just reaching the end of the
       block.

       To be more precise, "end" returns an object, that will execute the code when the object is
       destroyed; that is, when the variable assigned to goes out of scope. If the variable is
       lexical to the current block, the code will be executed when leaving the block.

       One can force premature execution of the code by undefining the variable assigned to, or
       assigning another value to the variable.

       "end" only takes one argument, a code reference. If one wishes the code reference to take
       arguments, wrapping the code reference in a closure suffices.

BUGS

       Due to a bug in Perl 5.6.0 (and perhaps before), anonymous subroutines that are not a
       closure will not go out of scope, not even on program termination. That is why "end" wraps
       the code fragment in a closure.

       There is a second bug in Perl 5.6.0 (and perhaps before) why this is necessary. If the
       code fragment isn't wrapped in another code reference, the original subroutine will be
       blessed in the package, making that "ref" on that code no longer returns the right value.
