# Read-Only Environment
|
|
|
|
## Summary
|
|
|
|
Add a way to access a read-only version of the environment without disabling `safeenv`.
|
|
|
|
## Motivation
|
|
|
|
There are valid use cases for accessing the environment in a read-only way. As defined in the [RFC](https://github.com/Roblox/luau/blob/master/rfcs/deprecate-getfenv-setfenv.md) for deprecating
|
|
getfenv and setfenv there are outlined cases where reading the environment is useful.
|
|
|
|
Increased performance can be achieved for transpilers written in Luau that may not be able to have a static environment created to access functions from or cant directly transpile 1:1. Similarly
|
|
interpreters written in Luau can benefit from being able to access functions without deoptimization, making other optimizations still active.
