Note, this approach is used in the Modelica modelling language since year 2000. In Modelica, it is more general: A description string can be added after every function definition, after every function argument and before every “;” of a statement/equation . There are then report generators that generate a pretty-print version, e.g. a list of all functions with just the function name and the description string; or a function with the input/output arguments in a table with description strings. Example:
Furthermore, tools provide the possibilty to pop-up an automatically generate GUI from the given information so that the arguments of the function can be given in this GUI and by clicking a button, the function is executed with the arguments provided in the GUI. Example:
