This is just to parse expressions *without* checking for defined
functions, and to be used in a first pass.

There is no good reason to have different syntax for variable and
function names, for example.

Also, we now define and use proper symbol and keyword parsers.

Some were clear bugs, generally there was some confusion between
expressions and terms.
The latter have now been subdivided into strong and weak terms, where
weak terms form the basis of expressions and strong terms are required
for function arguments.
