I checked also YAML, YAML::Syck, and YAML::XS --- all modules behave the same. Seems to be a general problem (or laxness) in Perl --- normally one does not need to care about this when the resulting data is processed with Perl programs, but I guess you need to interoperate with other programming languages, maybe via JSON...

The result is not the same with YAML::XS for 'canonical': $VAR1 = { 'canonical' => 685230, 'section' => { 'one' => '-1.056', 'empty' => undef, 'three' => '+33', 'Foo' => 'Bar' } }; Normally I use YAML::XS and I detected a difference by using the MongoDB driver.

You're right with YAML::XS. Still YAML and YAML::Syck make a PV of the canonical value. Show quoted text
