An object oriented interface to the Perl builtin tie(), that allows
a watchpoint to be placed on any Perl variable. A watchpoint is simply a
callback (subroutine) that is invoked when a variable is accessed.
The callback can do various things:
. alter a variable's value
. prevent a variable's value from being changed
. invoke a Perl/Tk callback when a variable changes
. trace references to a variable
perl Makefile.PL
make test
make install
You may find the programs in the .../examples directory interesting.
This version supports tied arrays and REQUIRES Perl 5.004_57 or
higher. Also, the old Delete() method has been renamed Unwatch()
since it conflicted with the builtin delete() function.
BUGS: not aware of any.
