Hi Sebastian,

first: thanks for your great work so far, I'm excited about the speed 
that this idea is getting concrete!

Great stuff and I think, it's a good alternative to the

Well, no beer is perfect ;)

nice collection!
some suggestions regarding the naming:

I prefer <f3:loop over="..." as="..."> over the for each syntax, as this 
reminds me too much of the PHP foreach, though it might be different 
(see below). But I guess, both is ok!

Regarding links and URIs (we decided to stick with "URI" instead of 
"URL" in FLOW3 context):
I wouldn't use the word "link" as top-level element. Actually it's more 
a "URI-helper" and link is one "sub-helper" (that's how it's handled in 
RoR too: 
So maybe it could be:

<f3:uri.linkTo action="...
<f3:uri.uriFor action="...


<f3:uri.tag action="...
<f3:uri action="...

Similar thing with the image:

<f3:image.tag maxWidth="...
<f3:image.uri maxWidth="...
if you only want to use the URI of the generated image..

Don't know.. I'm not perfectly happy with this either, but I think it's 
already a bit more consistent.

A few more helpers I can think of at the moment (some of them probably 
shouldn't  be part of the core though):

- Form (input, select, submit, ....) - That's probably provided by some 
form engine..

- Email (that's probably part of the URI helper)

- L10N... black hole ;)

- General formatters (raw, integer, float, rich text) -  by default 
{post.title} should be htmlspecialchar'ed of course.

- Grid <f3:grid headers="{col1:'POST ID', col2:'POST TITLE'}" 
columns="{col1:'id', col2:'title'}" for="{posts}" />  ...something like 
that - Or at least some general table helper.

And I think, there could be some more (optional) view helper parameters 

<f3:loop over="{posts}" as="post" key="index" counter="i"...

And all tag based helpers (image, link, ...) should allow all/most of 
the existing (X)HTML attributes like:

<f3:image width="..." maxWidth="..." title="..." rel="..." ...

Even though that would bloat the view helpers quite a bit (another 
reason why we should use view helper classes rather then methods to be 
able to extend some abstract "tagbased" view helper).

I'll be quite busy with the Routing until the first release. But I'll 
happily help wherever I can!
