The reason the syntax was rejected is that you can implement the exact same feature without special syntax. You could write: nt(a=1, b=2) and dynamically create a struct to store the data. In 3.6 this even preserves the order of the keyword

One advantage of namedtuple is that it is just a tuple! You can pass the namedtuple to code that expects a tuple, even C code that expects a tuple. This makes it easy to add names to tuples after the fact without breaking existing code. In

Python lambdas are just syntactic sugar for creating a function object. The ast can just build a named function and use it in the needed expression.

C uses {} for arrays and this is written in C.

Why was there so much Japanese traffic on the old nyaa.se (now nyaa.pantsu.cat)? Most of the raws are uploaded from Japan.

It is the other way around: just because the source is available free of charge does not make the software free as in freedom. For example, there are licenses that prohibit you from running the software for commercial use even though you ha

I don't think that it will ever work on PyPy. The data stored in the `co_code` field is a super set of the instructions python understands. The `co_code` data starts with a prelude which is the repl and builtin words, then there is a l

I hear this complaint about print all the time but I have never understood it. Why is print so special that it needs dedicated synta? Most languages don't do this and people don't seem to mind. Also, I almost never physically type

Why not send requests out of the blue? This happens to me all the time and I don't mind. It means someone cares enough to try to fix their problems instead of dumping it on me.

timeit does a run to decide how many loops to do, since it was much faster it ran it more times.

Hey, cool site. I work a lot with financial data and decided to poke at this, here are some thoughts / findings: - It would be nice to be able to look up companies by CIK instead of just ticker. - You should support share class delimit

What is a security vulnerability in a library here? Do you mean something like using `numpy.frombuffer` to mutate strings in place, or using `numpy.lib.stride_tricks` to access invalid addresses? Maybe this is something like functions calls

What does vulnerable mean in this context? Methods which forward input in a way that unlocks arbitrary code execution?

PyPy is still not really a performance option for numerical computing.

It is a little disingenuous to say that zipline doesn't support python, the short description from github says: "Zipline, a Pythonic Algorithmic Trading Library". Zipline also supports equities at minute and daily frequencies

At first glance you would think that python would be slower than C#; however, all of the real computation is happening in Numpy (C), Pandas (Cython which compiles to C), or in our own Cython. The extra overhead of the python is mainly domin

Could you explain why you feel that it is better? What in particular does LEAN support that Zipline does not support?

I think some of this might be addressed in the implementation section of the docs. http://quasiquotes.readthedocs.org/en/latest/impl.html To summarize: there is no import hook or ast parsing happening. Instead, th
