Hey, nice can of worms you opened here toma!

So here is a summary of what we've got so far. Let me know if you feel like adding more module/options or other fields:

Module Format In core Notes
Storable binary X fast
Data::Dumper text X widely used, need to eval the output to reload it
Data::Denter text   plug-in replacement for Data::Dumper
XML::Simple XML    
Data::DumpXML XML   more complete than XML::Dumper
XML::Dumper XML   simpler than Data::DumpXML
hash tied to a DB_File binary X  
AnyData various   can use CSV, XML, .INI...
DBD::AnyData various   same as AnyData with a DBI interface
Tk::Style XML   not on CPAN, for TK stylesheets
AppConfig text   configuration files can be overridden by command line arguments
Config::IniFiles text   MS-Windows style .ini files
Inifile text   MS-Windows style .ini files
Boulder text, XML   boulder format, plus various bio*-related formats

Update: added Boulder as suggested below.
