 Now we'd like to reuse it for generation of a more complex sequence:
 - first, digits `0..9` (with character codes 48..57),
-- followed by alphabet letters `a..z` (character codes 65..90)
-- followed by uppercased letters `A..Z` (character codes 97..122)

 We can use this sequence e.g. to create passwords by selecting characters from it (could add syntax characters as well), but let's generate it first.

 We can use async generators to process such data, but it's also worth to mention that there's also another API called Streams, that provides special interfaces to work with such streams, to transform the data and to pass it from one stream to another (e.g. download from one place and immediately send elsewhere).
