This is exactly my point: Because of the lousy parsing of the computer
programs, one is forced to do markup, so that they can get the information.

"... there are between three and \absolutelynomarkupwhatsoever{20} of these
creatures, according to the time of day..."
-- Long names make anything look useless. :-)

-- Again, if there was a better parser at hand, one would not need to have
any markup at all, because it would be able to see that `20' is the object
of type "number" and that `gamma + 1' is a mathematical expression. One
problem with TeX is that it does not have such parsing capabilities, and
that it is not possible to create well such objects, which could be later
used to determine the rendering style. (Like saying that single number
objects should be typeset in the text font, whereas math expression should
be typeset in the math mode.)
