This utility is intended to support the extension packages that are siblings of this package, along with third-party extensions, by providing a way to transform bodies in arbitrary ways. The "Deep" function then provides a means to apply a particular transform recursively to a nested block tree, allowing a particular extension to be supported at arbitrary nesting levels. This functionality is provided in terms of the standard zcl.Body interface, so that transform results can be used with any code that operates generically on bodies. This includes the zcldec and gozcl packages, so files with extensions can still be decoded in the usual way. |

zcl Extensions
This directory contains some packages implementing some extensions to zcl that add features by building on the core API in the main zcl 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.
