dynamically generate function in object

@Gordon, you say in other words that because in line #1 a new code-object - reference-object m (pointing to/referencing related machine object) - is created and then used in a function code-object and held in the array, the reference to m is held on to until the whole menuObject disappears / garbage collected... (Btw, since menuObject is not declared in function, its first use declares it as global and it survives the end of showMenu() function, and stays alive until set again as a new object (menuObjekt = {}), then the previous 'content' is garbage collected.
