Unfortunately, it isnt possible to add new kinds of statements to python.
you might want to have a look at Ruby, in which paren are entirely
optional. Ruby is similar to python in a lot of ways, but its also quite
different. It provides lots of syntactic sugar and a superior object
model, but its a resource hog compared to python.

You may also be interested in Logix. Logix is a language framework built
on top of python that allows you to dynamically extend python syntax at
run-time. Unfortunately, Logix is still rather new, and its incredibly
slow.
