Prework

• Read and agree to the Contributor Code of Conduct and contributing guidelines.
• If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.
• Post a minimal reproducible example like this one so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

Description

I just saw this in your recent commit so thought I should mention that there is no need for rlang / full duplicate. I am sure whatever issue it was for has been solved by other means. Also as of mirai 0.8.4, the daemons() status matrix is constructed on the client side - it is not sent as an object from dispatcher so there is no possibility of it being anything other than a simple matrix.

rlang::duplicate(
        mirai::daemons(.compute = self$name)$daemons,
        shallow = FALSE
      )

Thanks for the FYI, happy to remove calls to rlang::duplicate().
