when you want it to?

Why would you _want_ a function to segfault? That's like asking how to write a
function which tests that a computer is off after you pull the

Jesse Phillips:
It seems to be similar to that of std.typecons.Nullable with
the following differences.
Recently I've written something about Nullable:

Currently this code is not supported:
void foo(T)(T x, T function(T) f) {}
void main() {
foo(1, (int a) = a * a); // OK
foo(1, a = a * a); // Error
}
With the latest alpha compiler it gives:
test.d(4): Error: template test.foo does not match any function
template declaration.

Maxim Fomin:
The second is template lambda and templates have void type.
What you suggest here?
In D template functions become functions if they are passed where
the D compiler can infer their full type. This is correct code:
void foo(int function(int) f) {}
void main() {
foo(a = a *

I forgot there is int here, so T in lambda should be deduced as

I don't know where that cast occurs but I wanted to state the
obvious: Operator ~ is defined only for arrays.
Would having it also work for individual units to make an array
be a plausible enhancement request? It would seem like a natural
use of the operator.
Philippe Sigaud:
Doesn't that mean you're asking the compiler to have a full
unification
engine? Your example is simple, but the general case is more
complicated:
I think the general case doesn't require a whole program type
inference, just a local one. But maybe it's too much complex to

Try to declutter your code as much as possible, then print the

Am I right that my variant of code would be valid for C#?
How can I assign value to name in such manner?
When I should use keyword this?
I dropped it from my class and now I can make instance of class
without in sych way:
auto file = new GetFileName();
file.name = test;

Ok so I have the need to make a static library that will be
reused in multiple future projects. My thinking was that in
future solutions i can just add an existing project, my static
library project, so it would grab it and just work. However i

Indeed. If you have not defined a constructor, the language defines one
for you, which
