More precisely, I should say that this kind of changes to the syntax and bytecode compiler are *really* uninteresting from our point of view. PyPy is indeed about language implementations, but not about the syntactic level. There are nice existing tools about generating parsers in various languages; and as each of them has some issues with the Python language, we just wrote the parser and compiler by hand and happily forgot about it. Instead, PyPy is about implementation features. Moreover, it focuses more on features that can be meta-programmed, like the stackless transformation (which works fine so far, and which does not need any change to support e.g. various kinds of Select).
