   Sorry, just realised I should have added:

   More fundamentally, work out how to do *one* thing (convert a
string to a length+data binary), then use the list functions to
map/filter/fold many of those into one result.

   Occasionally, you'll have to write a recursive function directly,
but it's rarer than you might think.

   Hugo.
