Problem code:
[[code]import std.ctype;
import std.string;
void main()
{
char[] s = "some string";
s = toupper(s);
printf("%.*s\n", s);
}]

Error message:
[[code]c:\dmd\bin\..\src\phobos\std\string.d(502): function toupper
conflicts with ctype.toupper at c:\dmd\bin\..\src\phobos\std\ctype.d(36)]

There are multiple solutions. The simplest is to change [[code] s = toupper(s);] to [[code] s = std.string.toupper(s);]

== A struct is not a valid initializer for an array =

Problem code:
[[code]
int[] data = { 17, 23, 42, 69, 105, 666 };
]

Arrays are initialized using square brackets []
[[code]
int[] data = [ 17, 23, 42, 69, 105, 666 ];
]

Structs are initialized using braces {}
[[code]
struct Foo
{
int A;
char[] B;
}

const Foo X = {1, "abc"};
]

To combine them:
[[code]
struct Foo
{
int A;
char[] B;
}

const Foo[] X = [ {1, "abc" },
{4, "xyzzy" }
];
]
