I thought that's what the following proposal was all about? :S
http://dev.zope.org/Wikis/DevSite/Proposals/DTMLExpressionSyntax

The idea being to have the form:
<dtml-TAGNAME ATTRIBUTE-FORMAT="VALUE">

instead

where FORMAT is in effect the type...

...or have I got that wrong?

Hurm, have I duplicated that with this?
http://dev.zope.org/Wikis/DevSite/Proposals/GenericMethodInterface

If so, how do we squish the two together?

How about having a 'Method' base class for _all_ methods, as I suggested
in my proposal, which would provide the calling interface as well as
some standard 'Method' management tabs?

I like the idea of having a bindings tab and an argument tab. Why is
that a bad idea? :-)

I'll do that in a sec :-)

Hmm, might make more sense when I play with it :-)

Cool, is this going toward what I was saying about Zope having a generic
'Method' interface?

Hehe :-)
