[Help-smalltalk] iliad and blocks

[Paolo Bonzini]

Hi, I was going to write this as a comment to one of Joachim's post but 
maybe it's better to post here.  The relevant post is 
http://smalltalk.gnu.org/blog/joe/one-step-further-iliad and some 
comments may not make sense without referring to there.

Joachim builds a PageTemplate widget, and I'm not sure I like the idea 
of returning blocks from the methods there (like #mainContent).  I would 
rather use something like #renderMainContentOn:

UrPics.PageTemplate subclass: UnknownHome [
    renderMainContentOn: e [
        e h1: 'UnknownHome Object!'.
    ]
]


Another idea could be to add

BlockClosure extend [
    renderOn: e [ self value: e ]
]

and implement Widget>>renderOn: like this

renderOn: e [ e add: self build ]

This way, you could simply return "^Login new" from the message #login 
in Joachim's Menu widget.

Now maybe I misunderstood Iliad's architecture (which I haven't looked 
at in detail yet), so the above does not make sense.  Just throwing 2 cents.
