# Description `Value` describes the types of first-class values that users and scripts can create, manipulate, pass around, and store. However, `Block`s are not first-class values in the language, so this PR removes it from `Value`. This removes some unnecessary code, and this change should be invisible to the user except for the change to `scope modules` described below. # User-Facing Changes Breaking change: the output of `scope modules` was changed so that `env_block` is now `has_env_block` which is a boolean value instead of a `Block`. # After Submitting Update the language guide possibly.
