You can define a `toString` method, like this:
```d
string toString()
{
import std.conv;
return p.to!string;

I just want to share a view lines of code.
The availability of operator overloading can result in very short
and precise code for linear algebra.
To test/explore it a little I just modified the alias this
example:
```
#!/usr/bin/env rdmd
struct Point
{
double[2] p;
// Forward all

Hi! I'm trying to make my own string type for my library. Anyway,
I'm not very experienced with structs/classes so I don't
understand what's going one here. I will not post the full code
because I don't think that anyone would like it so I will just
post the important parts that play a role

Hi all,
I'm trying to figure out the most efficient way to create
modified instances of immutable structs.
Currently, I'm doing the following:
```d
immutable struct Node {
string label;
Node parentNode;
NetworkPort port;
auto withLabel(string newLabel)
Let's say I want to write a simple program that asks for an input
of a single character.
After pressing a single key on a keyboard, the character is
printed out and the program should stop.
Got a suspicious interface instance in the debugger and question
myself:

This might not be the best way but it is a kinda cool trick
anyway: structs have a `tupleof` property you can slice. So you

Yeah, the getch function in there builds on the rest of the
