I do have a plan to add a function to obtain a token from the source,
either with or without expnasion - but in the latter case still going
through the same parser.
Using it in a few places (ie the LHS of assigments and dependencies, and
the arguments of conditionals) would remove a lot of the places where
text is parsed more than once.

Unfortunately I need to more quickly correct some of the existing code
first - since the the change to the .for loop expansion has exposed
some code that only worked with .for loop control variables.
