Yeah. Python is a great language for glue. Glue does not need to be fast, it's hopefully small in scope, and it has (hopefully) one or few jobs. Python can be a great frontend to faster C code, but sooner or later it starts being the bottleneck where it matters. These pseudo-Python compiler/interpreters are... cool, I guess, and might even solve that problem in some cases. The issue is half of them target the syntax of Python, rather than integrating with the runtime (really, CPython). The problem, I think, is that we have huge applications implemented from top to bottom in Python where the bottleneck is... everywhere and there is no good solution that isn't somehow writing a faster Python implementation (Pypy will get you far) or rewriting it all in a different language.
