But all data has a lexical representation, whether or not it also has a
data type. I still do not understand why the presence of a data type makes
it harder to take advantage of the lexical representation. I know that a
lot of people on this list believe that it does - and vehemently believe
that it does.
I would still like to see some examples that illustrate the alleged
problem, preferably with real code and angle brackets. I need a more
concrete understanding of what is actually being said.
