In most applications it's possible to fully evaluate configuration at the beginning and work only with resolved values after that, but in some unusual cases it's necessary to split parsing and decoding between two separate processes connected by a pipe or network connection. hclpack is intended to provide compact wire formats for sending bodies over the network such that they can be decoded and evaluated and get the same results. This is not something that can happen fully automatically because a hcl.Body is an abstract node rather than a physical construct, and so access to the original source code is required to construct such a representation, and to interpret any source ranges that emerged from the final evaluation.
