Such env var would be helpful on HPC computing. Indeed most of 
worldwide grid use the "environment module" -> 
https://github.com/cea-hpc/modules
I found this article which describe well this technology: 
https://www.admin-magazine.com/HPC/Articles/Environment-Modules

In short to allow multiple version of same tools, "environment 
module" use PATH, C_INCLUDE_PATH, LD_CONFIG_PATH, PYTHONPATH and 
others to reach this goal.

But in D that seem not easy to do it as this env var do not exist.
