| Subject: | Modification of non-creatable hash value attempted |
Try this :
Show quoted text
> use YAML::Syck;
> $a = YAML::Syck::Load("SID:\n type: fixed\n default: ~\n";
> $a->{SID}->{default} = 'abc';
Returns :
Modification of non-creatable hash value attempted, subscript "default"
If you change the initial value of default: to '' or '123', then
resetting the value works.
If you use YAML instead of YAML::Syck, this works as well.
