+ * Consider the following ES5 code that may have been generated for a class:
+ *
+ * ```
+ * var A = (function(){
+ *   function A() {}
+ *   return A;
+ * }());
+ * A.staticProp = true;
+ * ```
+ *
+ * Here, TypeScript marks the symbol for "A" as a so-called "expando symbol", which causes
+ * "staticProp" to be added as an export of the "A" symbol.
+ *
+ * In the example above, symbol "A" has been assigned some flags to indicate that it represents a
+ * class. Due to this flag, the symbol is considered an expando symbol and as such, "staticProp" is
+ * stored in `ts.Symbol.exports`.
+ *
+ * A problem arises when "A" is not at the top-level, i.e. in UMD bundles. In that case, the symbol
+ * does not have the flag that marks the symbol as a class. Therefore, TypeScript inspects "A"'s
+ * initializer expression, which is an IIFE in the above example. Unfortunately however, only IIFEs
+ * of the form `(function(){})()` qualify as initializer for an "expando symbol"; the slightly
+ * different form seen in the example above, `(function(){}())`, does not. This prevents the "A"
+ * symbol from being considered an expando symbol, in turn preventing "staticProp" from being stored
+ * in `ts.Symbol.exports`.
+ *
+ * The logic for identifying symbols as "expando symbols" can be found here:
+ * https://github.com/microsoft/TypeScript/blob/v3.4.5/src/compiler/binder.ts#L2656-L2685
+ *
+ * Notice how the `getExpandoInitializer` function is available on the "ts" namespace in the
+ * compiled bundle, so we are able to override this function to accommodate for the alternative
+ * IIFE notation. The original implementation can be found at:
+ * https://github.com/Microsoft/TypeScript/blob/v3.4.5/src/compiler/utilities.ts#L1864-L1887
