D is mentioned in the article, and I'm starting a discussion comparing 
the relative merits of two schools of thought for concepts.

I think he means dynamically typed languages. An example of partially weakly
typed language is C. For example Python3 is almost as strongly typed as D.



Concepts do introduce a lot of complexity into the language but they reduce and
organize the complexity of programs.<



There are features more important for library developers and other features
that are enough for application writers.



In Java, everything is an object,<



Except native values as ints, etc.

It's a nice article that has taught me several details I didn't know about.
This is the tutorial on Concepts I have appreciated more:

I made the same exact point while reviewing! I'm not sure why he stuck 
with the "weakly" misnomer. Here's my comment:

===========
"weakly typed languages" -> "dynamically typed languages" throughout 
(just to avoid antagonizing anyone gratuitously, plus it's more correct 
as C is weakly typed but can't detect type errors).
===========


 For example Python3 is almost as strongly
 typed as D.

 they reduce and organize the complexity of programs.<

 features that are enough for application writers.



Yah, though I pointed out that dedicating too complex features to the 
very few is an indication that something has gone wrong in the design of 
the language. It's the beauty-of-the-part at the expense of the whole 
fallacy.

With the invention of copy/paste, I find that things like tinyurl are only 
useful for when you need to read off a url over the telephone (or rickroll 
someone), or something like that. Which is to say, practically never.

Ugh, don't even get me started on twitter... Although I guess one thing I 
could say about it is they did a very good job naming it...Or at least the 
first 4 letters...

Twitter has its niche. I found it to be useful for announcements about D, as 
people who are interested may not be interested in regularly checking the n.g.
