# HCL Extensions | |
This directory contains some packages implementing some extensions to HCL | |
that add features by building on the core API in the main `hcl` package. | |
These serve as optional language extensions for use-cases that are limited only | |
to specific callers. Generally these make the language more expressive at | |
the expense of increased dynamic behavior that may be undesirable for | |
applications that need to impose more rigid structure on configuration. |
