Compatibility with C extensions seems to be the most difficult thing for an alternative implementation to achieve. PyPy struggled with this for a long time, and IIRC extension compatibility also caused the failure of Dropbox's Pyston.

It's a really good article! Nothing too advanced, but concisely explains a lot of the basic concepts of both a compiler and an interpreter.

Isn't this how Python itself implements function calls, using the host (C) stack? Hence Python's lack of support for stackful coroutines?

That's right - Guido has been very much in favour of adding type hints to Python. Are type hints Pythonic? I personally don't think so - to me, they don't match the philosophy of the rest of the language. On the other hand, o

Isn't Nim, like Python, a large, complex language? Looking at the documentation, it seems to include a huge number of features.

The Python equivalent of your JavaScript example is simply: def double(x): return x * 2 Python's `lambda` construct creates anonymous functions - its limitations mean it should only be used when anonymity is required. If a fun

Would it be possible for Python's parser to handle the infix `->` syntax, without making it more complex than the current LL(1)?

I've heard of this - people considering Python 2.7 as an "LTS" version of the language, receiving bug fixes but otherwise remaining unchanged for many years. I wonder, once 2.7 is EOL in a years time, whether the language dev

No, IMO. Don't get me wrong, Python 3 is a better language than Python 2. I just don't think it's that much better that it was worth breaking backwards compatibility and stalling the language for several years. Python 3 did

Is anyone using VirtualBox on the desktop? Specifically, to run Linux/macOS/Windows guests on a macOS host? Would you recommend it? Or is the best option VMware Fusion, Parallels, or something else?

You're right, this is the same problem that Python has with closures, for example: >>> l = [] >>> for i in range(10): ... l.append(lambda: i) ... >>> for j in range(10): ...

Your `f` is not a method, but a top-level function whose first parameter happens to be named `self`. You can't call `f` as a method of any object, because in Python (unlike Ruby) the top-level namespace is unrelated to the namespaces

There doesn't seem to be any interest in checking type annotations at run-time. Unfortunately, without doing so, type annotations look authoritative but are essentially just comments. I believe Julia is an example of a dynamically-type

You can't add methods to integers in Python, but they're still objects in the sense that you can call methods on them: >>> i = 123 >>> i.bit_length() 7

Regarding reason 3 (syntax), I don't mind significant whitespace in itself, but it has knock-on effects which can be problematic. It's the direct cause of Python's `lambda` limitations [1], and IIRC the lack of an explicit en

Python is, despite its simple appearance, a much more complex language than JavaScript. A V8 equivalent for Python is certainly possible, but would require even more work than went into creating V8 itself - who would be motivated to spend
