“Sugar” is, to a certain extent, in the eye of the beholder—at least when
it 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 one
wants to be forced to do without the extra syntax—at least not for their
favorite pieces—but it is worth looking at how a language’s constructs can
be built from the core. That is just what Brett Cannon has been doing for
Python, on his blog and in talks,
including a talk at PyCon back in April (YouTube video).
