 ### Utility Functions ###
 
+* **`throwableError (Message:string):Error`**<br>this function has been provided in order to simplify the construction of "named" `Error` instances: if the given `Message` starts with a JavaScript identifier followed by a colon, identifier and colon are stripped apart and the identifier is used as the `name` property of a newly constructed `Error` instance for the remaining part of `Message`. Otherwise, this function is equivalent to `new Error(Message)`
 * **`throwError (Message:string):never`**<br>this function has been provided in order to simplify throwing "named" `Error` instances: if the given `Message` starts with a JavaScript identifier followed by a colon, identifier and colon are stripped apart and the identifier is used as the `name` property of a newly constructed `Error` instance for the remaining part of `Message`. Otherwise, this function is equivalent to `throw new Error(Message)` <br>&nbsp;<br>
 * **`ObjectMergedWith (TargetObject:object, ...otherObjectList:object[]):object`**<br>`Object.assign` can not be used to copy properties with getters and setters from one object into another - this is what `ObjectMergedWith` is good for: it copies the descriptors of all *own* properties from any object found in `otherObjectList` into the given `TargetObject` and also returns that object as its function result. Any  descriptor already existing for a given property in `TargetObject` will be overwritten<br>&nbsp;<br>
 * **`constrained (Value:number, Minimum:number = -Infinity, Maximum:number = Infinity):number`**<br>limits the given `Value` to the range specified by `Minimum` and `Maximum` - i.e., the function returns `Minimum` if `Value` is less than (or equal to) `Minimum`, `Maximum` if `Value` is greater than (or equal to) `Maximum`, or `Value` itself otherwise. `Minimum` and `Maximum` are optional and default to `-Infinity` or `+Infinity`, resp.<br>&nbsp;<br>
