Hi All,
Is there a namespace I should implement in Raylib? For example,
I cannot compile without writing Colors at the beginning of the
colors: ```Colors.GRAY```

Assuming you mean the raylib-d binding, it implements the values
as a named enum, so the `Colors` namespace is required.
https://dlang.org/spec/enum.html#named_enums
If you have a situation where you need to type it multiple times
in consecutive code lines, you can use `with`:
```d
with(Colors) {
}
```
Then you can drop the namespace and just used the values. Very
useful for switches:
```d
with(Colors) switch(myColor) {
}
```
You can also generate aliases, so that e.g., `LIGHTGRAY` is
equivalent to `Colors.LIGHTGRAY`). Just throw this template
function in an appropriate module:
```d
enum expandEnum(EnumType, string fqnEnumType = EnumType.stringof)
= (){
string expandEnum;
foreach(m;__traits(allMembers, EnumType)) {
expandEnum ~= "alias " ~ m ~ " = " ~ fqnEnumType ~ "." ~
m ~ ";";
}
return expandEnum;
}();
```
Then you can mixin aliases for any named enum members you'd like:
```d
mixin(expandEnum!Colors);
```
