Large parts of Emacs are indeed implemented in Emacs Lisp. There's are some

So, firstly, does that work? Answer: i've tested it a it, and yes.
Secondly, do you really have to do this just to parse a date with a

Greetings,
I need a little help with buffer objects. Many Python objects export
the buffer interface, or can be persuaded to create a buffer object
with a buffer() call.
First question, the buffer() function appears very quick. Does it just
wrap the internal pointer and then exit?
Second questio

Really what we're talking about here is weak typing in the form of
optional type hinting performed on a function by function basis. As an
option, what it would do is allow an author to semantically 'hint' to
the interpreter that a function is expecting a certain type, and
perform any implicit conv
This type of hinting would only break type ducking in-so-much as a
function that leveraged that hinting would be looking specifically for
an instance of a particular type, which would be absolutely no
different than a developer performing the type check manually and
throwing it out if the type were
I don't use isinstance() and type() at all, nor am I testing the type

is a semantic safety mechanism that is neither required, nor imposed.
Ultimately what it looks like what I'm proposing is a syntactic
shorthand for the adapt

realize, to be perfectly safe, especially when the iterable can

That's not a bad idea. Another nice feature is support for callable

raising an exception when you really want that (i.e. if not finding a

I wonder if the OP is trying to find out whether python programmes can

what they're after.)

Maybe the IDE is the best place to warn you of something like that.
You could have an IDE where you specify which language you're more
familiar with and then have it display warnings likely to be relevant
to you. People could collaborate to add support for gradually more
niche languages.
