I'm trying to get the values of an enum at compile-time and
running into a behavior I don't understand.
Consider the following enum:
enum A {x="foo", y="bar"}
And now, I just want to print out the values of A at runtime
(e.g. A.x = "foo").
void main()
{
static foreach(i, op;
```p.d
module pp;
void foo ()
{
import std.stdio: writeln;
__PRETTY_FUNCTION__.writeln;
}
```
```x.d
import p;
```
```main.d
import x;
unittest {
import pp: foo; // wrong name is accepted if x is imported
// import p: foo;
foo;
}
```
$ dmd -i -unittest -main -run main
void

Phobos's enum conversion always looks at the identifier, whereas
the rest of the language looks at the value. Remember phobos'
writeln forwards to the rest of its conversions just like

Enum to string conversion is usually implemented using the name
of the enum member, regardless of
Module names and file names are completely independent on the
language level. You can have a file `whatever.d` with `module
foo.bar.totally.different;` and `import
foo.bar.totally.different` and it all works as long as you add
the whatever.d to the build.
The only reason people recommend

That one `import p;` is kinda weird, it should probably
complain then you imported one thing and got another, but
generally the name not matching is no problem at all.
```main.d (version 2)
// import x;
unittest {

Also wanted to note that if I do:
string enumValue = op;
writeln(enumValue);
Then it also outputs foo and bar. So, why would the behavior of
op.to!string not be the same?

Hi,
lets say i want to create a function that returns multiple values
- e.g. Tuple!(string,string).
Why/when i should prefer Tuple as a return type over returning a
struct (or even string[2] in this case)?
Thank you

A Tuple is just a struct declared inlined. I personally use
struct every single time - structs can be separately documented

Nah, this is old. It is also bad D code.
Allocate up front and then set.
