[TYPO3-mvc] FLUID: extended loop features

[Franz Koch]

Hi,

>   <f:if condition="{row.isFirst}">  ...</f:if>
> </f:for>
> <p>{data.total} items listed</p>

I can only second that. Those features are quite handy and should be 
part of FLUID (if not already there, hidden under some stone)

> loop.total
> iteration.index (0 based)
> iteration.count (1 based)
> iteration.isFirst
> iteration.isLast
> iteration.isOdd
> iteration.isEven

looks good.

Yes, I'd say to move it to the iteration object. But then "count" could 
be misleading as it could also deliver the total count. So I'd say:

iteration.index (0 based or SPLObjectKey)
iteration.cycle (1 based)
iteration.total (total count)


Btw. - I'm also in favor or your other suggestions - those are quite 
useful and simplify templating a lot (especially the optionSplit 
equivalent).
