This data structure would require extra checks of the values (i.e.
ref($hash{'joe'}) eq 'ARRAY' ? $hash{'joe'}[0] : $hash{'joe'}) each time you
do a lookup. To simplify access it should probably look more like:
%hash = (
joe => ['smith'],
jim => ['jones', 'taylor'],
sof => ['comes'],
);
References and complex data structures are covered in perldoc perlreftut,
perldoc perlref, perldoc perldata, perldoc perllol, and perldoc perldsc.
