Subject: | booleans are readonly constants |
YAML such as "key: true"
becomes, in perl, "key: 1"
which is expected.
However this value is a readonly constant (PL_sv_yes)
- this is done by LibYAML/perl_libyaml.c
This causes problems when running the results of LoadFile() through
Data::Visitor to munge the data.
Is it necessary for this to be PL_sv_yes, rather than just a normal scalar?
