If a diagnostic occurs while we're evaluating an expression, we'll now include a reference to that expression in the diagnostic object. We previously added the corresponding EvalContext here too, and so with these together it is now possible for a diagnostic renderer to see not only what was in scope when the problem occurred but also what parts of that scope the expression was relying on (via method Expression.Variables).
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.
