proc buildName(n: NimNode): string {....raises: [ValueError, Exception],
                                     tags: [RootEffect].}

Builds the formula name in a lisp like representation. Only for debugging and printing purposes. Source   Edit  

proc buildResultColName(n: NimNode): NimNode {....raises: [], tags: [].}

Builds the name of the resulting column name of a formula. Mainly it simply uses the node as is, except for column references via accented quotes and call string literals, in which case we simply use the string values underlying. We need to be able to use symbols from the local scope (or possible proc calls) to determine the resulting column name at runtime. Source   Edit
