Depends a lot of your style:
In my DSL I use at work I will write stuff like

client :name => "allow ssh to DB", :server => "1.1.1.1" ...  do
end

If you leave the parens away the {} just will not work, so this for
sure is a nice feature for a DSL. That does not necessarily make it
the best "Programming Style".
Personally and sorry for insisting just find hat

def recover parms = {}, &blk
...
recover :from => :error do some_stuff end
...

reads better (for me) than
def recover( params ={}, &blk)
...
recover( :from => :error ){ do_some_stuff }

I dislike parens, but I am pretty alone, so I gotto refrain from
repeating myself (still hoping for some support here, obviously ;)
