Well, it depends on the language. Some are quite good at restricting programs so that it is not possible to execute arbitrary code. Take a look at https://propellor.branchable.com to see how Haskell might be used. Idris might be a good candidate as well. https://dhall-lang.org is quite interesting for these purposes as well (although it is not general purpose). - Source: Hacker News / 10 months ago
Have a look on Rex - https://rexify.org, in addition to dsl like constructs it is just pure perl. It also doesn't need any dependencies on the managed host, just perl and ssh. Source: over 2 years ago
Since I feel that rex needs more attention, here is a small example from $work using rex. Needed to quickly reconfigure a number of Ubuntu hosts with netplan to use static ip addresses instead of DHCP. Source: almost 3 years ago
