+    This pass adds a `reflectionMap` field and an accompanying `getBufferForName` method to 
+    EmitC classes, enabling runtime lookup of class fields by name. 
+    This requires that the class has fields with attributes.
+    Each `emitc.field` is expected to have an attribute (configured by the
+    `included-field-attrs` option) that is an array containing a single string
+    attribute. If a field possesses both an attribute specified by
+    `included-field-attrs` and an attribute specified in `excluded-field-attrs`,
+    the `included-field-attrs` attribute takes precedence and the field will be
+    included in the reflection map.

Then it's a win-win :)
