Agreed

Agreed

I have almost never used inline assembler even in languages that
support it. Of course, this is only a sub-point of your point 6:
using inline assembly in a language as slow as Python would be
completely pointless.

I would not count them as advantages per se. Some of their
consequences might be seen as advantages once we have enough
experience with them.

Agreed

Python has it too (since 2.6 IIRC, see the "with" keyword).
Moreover, Python makes it clear that RAII is happening by requiring
a special syntax at the call point.

> 8. direct interface to C
Cython gives it too: it is as easy to write a Cython interface
module as to write a D interface file for a C library.

> 9. templates
Since Python uses duck typing everywhere, you could argue that
everything in Python is a template.

> 10. CTFE
This is not an advantage per se. It is useful because it allows
generative programming, so see point 11.

> 11. generative programming
Python has that (like most dynamic languages) through "eval".

	Well, that makes it 3 valid points out of 11 still ;)
