imho that doesn't contradict me (at least what I wanted to say :-)
In the example I quoted, the compiler (parser?) would have to look at
the previous line (a := 14.) to know that in the current line
(b := - a.) a is representing a number. Only then it makes sense to
try building a literal.
I was not successful in finding senders of nextLiteral in Scanner or
Parser so I still don't know. Also no luck with searching all sources.
Only hits in xml-parser which is a different beast.
Thanks for your patience anyway!
