[TYPO3-v4] Array support for cObject (was: Re: [TYPO3-core] RFC #17420: Add LOOP cObject)

[Ernesto Baschny [cron IT]]

Hi Xavier,

I think this its going in a nice direction here.

But I would prefer to discuss the specifications of it first in the v4
list, and maybe gather some suggested syntaxes via Wiki. I think it has
to be a team efford to bring this new functionality to the core, and I
guess plenty of people have thought about it already.

For example, your particular suggestion below (ARRAY cObject):

I would prefer that a cObject (upper case object) *always* returns a
string (render() returns a string as of its abstract super class).

So in my eyes, it should be some new function which returns arrays for
other TypoScript methods to work with.

For example just like the "select." returns a SQL resource, an "array."
stdWrap method could return an array etc.

What do you think?

Cheers,
Ernesto
