Delphi/Pascal and Wolfram mathematica are the two things I point people to when we talk about documentation. Every single function had a working snippet example. Mathematica had details and applications for each function, while Delphi/BP had a well written explanation of what the function would do and how to use it. They are the standards that have not been surpassed yet. Or even approached imho. These days you get an auto generated docstring explaining that xval is "the x value passed to the function".
