This is plain wrong.
How do you do closures in C/C++?

Function-objects. (Examples in STL.)

What about higher
order functions,

Function-objects plus tuple types. (Tuple types in latest C++ standard, I
think; In Boost anyway.)

pattern matching,

That same way it's done it other languages, either statically (in C++ using
templates) or slowly and painfully.

dynamic typing?

Bah. As long as the language is strongly typed, I prefer all my types to be
static. Type errors should be detected before run time. [I'm only willing
to let value errors slip until run time so I can accept user input. ;)]

Still. C++ is neither strongly nor dynamically typed, which is quite
unfortunate, but are language choices. In comparision, it would be fairly
impossible to "do" weak, static typing in Ruby or Python, too.

I don't agree with the OP, though. Languages like Perl, Python, PHP, and
Ruby allow you to trade off (very little) run time or memory for (usually a
lot) of man-hours. CPU cycles and RAM is much cheaper than Labor costs at
those ratios, and *all* of those languages have some way of calling into
C/C++ for things that just have to be written in those languages.

I think the OP need to spend some time with Haskel, Erlang, Prolog, and
Lisp. <tease>Only *then* can you truly learn to *hate* non C-based
languages. ;)</tease>
