Or slashes could be used for namespacing:

(env/TERM "screen")
(env/LANG "en_US.UTF-8")
(java-system-properties/java.vm.name "OpenJDK 64-Bit Server VM")
(java-system-properties/java.vm.version "12+33")

This seems the best alternative to me:

* Scheme code can just do (assoc 'env/LANG ...) instead of manually
splitting strings at #\= to get the name and value.

* Awk, grep|sed and other regexp tools can work with them like normal
properties.

* Don't need to worry about how to merge multiple (env ...) lines into
one alist.
