Your example data used YAML; I used an appropriate module to get that data into a Perl data structure.

My point, however, was not about YAML; it was in relation to old and new syntax.

hippo had already shown how to get a single array element:

$session_data->{azuread}{login_info}{roles}[0]
[download]

I showed a newer syntax for getting the entire array:

$session_data->{azuread}{login_info}{roles}->@*
[download]

Your post resulted in further discussion of old/new syntax. It was an interesting conversation; so, thanks for that.
