Protected attribute for variables in derived types

[aradi]

It would be awesome, if the protected attribute could also be used in derived types:

  type :: some_big_data_t
    real, allocatable, protected :: data(:,:)
  contains
    procedure :: set_data
    !procedure :: get_data
  end type some_big_data_t

It would help to avoid unnecessary copies when retrieving data from a derived type instance and enable protection against unnoticed manipulation of that data.

Thanks @aradi for the idea. Would you be interested in putting a proposal together for this? You can send a PR with the draft.

[aradi]

Yes, sure, why not. I'll make a proposal.

Stupid question: How do you choose the file name for the proposal in the PR?

[certik]

Just choose some, we can rename it later.
