A few months ago, Aleksey posted a cool way of doing lambda using function
notation. I hadn't followed the thread at the time, but I read up on it
recently. Like many others, I found it hard to understand how it worked, so
I asked Aleksey if he could make a minimal example of it, which he did.

Yeah, I had considered using function types as "lightweight type
vectors", but gave up for this reason.

Yep.

They are stripped on non-class rvalues,

What is the point of what exactly? Of yet another lambda notation? Of round
brackets? Of my post? :)
Anyway, there wasn't much of the point besides demonstrating that something

If you are tired of angle brackets in your templates (no, it's not a TV
commercial :), may be you'll like this one:
typedef eval<
count_if(
list(int,char,long,int)
, lambda(is_same(_,int))
)
