TODO for perl module Text::TemplateFill

This is as much things that I don't think should be added as well
as things that I would/might like to.

It is understood that any contribution that is sent in for distribution
with this module shall have copyright assigned to addw who will release
it under the same licence as the rest of the module. Contributions will
be acknowledged.

More test cases. In fact the current test program is more of a demo,
it is the stripping out of part of one of the first uses of this module.


More examples, a random list of things that should be shown:
* Date formatting
* Accumulation of a variable (eg number of widgets sold)
* The different options (SetOpt)
* Accessing of variables in different paragraphs


Conditional use of paragraphs. The sort of thing that I have in mind is
when processing sorted data a page break might be forced when one of the
variables changes.
There are a couple of different cases:
* Substitute a different paragraph
* Insert a paragraph before the requested one (eg insert page break).
This is easier now that Math::Expression is used.
The obvious way would be to have a different set of ${Calc directives that
were evaluated before the decision is made if the paragraph will fit on
the current page. The choice of new page might be done by setting a special
variable - keeps the syntax simple. Eg:
	${ParaCalc LastSupplier ne Supplier ? INSERT_PARA : dummy := ( 'Footer', 'Header' ) }
This compares the supplier name with the last one, if it is different
INSERT_PARA is assigned to otherwise a dummy variable is assigned to.
What is assigned is a list of two paragraphs, one to end the current page, the next
to start a new one. More thought needed.


The reading in of a paragraph causes the reading in of other paragraphs. This
means that paragraphs can be added by, say, a translator - paragraphs that
the original programmer did not forsee. This would be particularily useful
with conditional use of paragraphs. Eg:
	${ReadPara Para1 Para2 }


It would be nice to use the Math::Expression ability of specifying a different
function evalutation function. This would yeild the possibility callbacks in
paragraphs to the main program. So you have a part-number and want it
description, price, weight, ... 
Why not just pass this information in bound varaibles ? Well, computing it
might be expensive and so only do it if the paragraph really needs it; anyway
this would be a cool thing to do.
