Error, String: cannot convert a into a string in
String( a ) called from
main loop

That is annoying! Is there any reason why the String function shouldn't
convert the abstract generator into the supplied string? That ought to
be exactly what the string is there for. And similarly for words in
abstract generators. Is there any other way of getting the printing
string for a word, other than by doing something silly like writing
to a file enclosed in quotes, and reading back in?

Best wishes,
