Actually I did want it, but I thought maybe no one would notice and I could 
just concentrate on convincing people that method arguments are good before 
dealing with constants ;-)

Maybe.

Are single quotes more common than commas? Would the strings that you pass 
into methods be long ones? I would have thought that long strings tend to be 
static parts of the HTML doc or are stored in variables. Do you have lots of 
python: calls in your current template that include long strings?

I think 

param:more='...'
param:more=this/thing

might be more suitable. I'm not a Python person so I don't mind too much!

In the end the whole idea is to make it easier to do the simple, useful things 
are currently done with a quick "python:". I also think it's quite strange 
that you can call methods using TALES but you cannot pass arguments,
