[$] Python is (mostly) made of syntactic sugar

"Sugar" is, to a certain extent, in the eye of the beholder-at least whenit comes to syntax. Programming languages are often made up of a (mostly)irreducible core, with lots of sugary constructs sprinkled on top-the syntactic sugar. No onewants to be forced to do without the extra syntax-at least not for theirfavorite pieces-but it is worth looking at how a language's constructs canbe built from the core. That is just what Brett Cannon has been doing forPython, on his blog and in talks,including a talk at PyCon back in April (YouTube video).
