proc rememberExpansion(c: PContext; info: TLineInfo; expandedSym: PSym) {.
    ...raises: [], tags: [], forbids: [].}
Templates and macros are very special in Nim; these have inlining semantics so after semantic checking they leave no trace in the sem'checked AST. This is very bad for IDE-like tooling ("find all usages of this template" would not work). We need special logic to remember macro/template expansions. This is done here and delegated to the "rod" file mechanism. Source   Edit
