Finished the x20 example.  This PerlDL example completely replicates the functionalities of the equivalent x20c demo, including mouse interaction, thanks to the implementation of plGetCursor in the PerlDL binding.  This makes Perl the third better supported binding for PLplot, just behind C and C++.
