You can use symbolic references for this purpose:
http://perldoc.perl.org/perlref.html#Symbolic-references
But this is a highly-unrecommended way, because if you'll get symbolic
names from external souce (e.g. a file) they may interfere with other
variables or built-ins.
It's much better to create a hash of hashrefs in you case.
