+Syntax highlighting for D using Pygments:
+
+<highlight lang="d"><![CDATA[
+import core.stdc.stdio : getchar, printf;
+
+extern(C) void main()
+{
+    slide: for (auto q = 0u, i = 1u; q & 0xffu ^ '\n'; ++i)
+    {
+        q <<= 8u;
+        q |= getchar();
+        if (i < 4)
+            continue;
+
+        auto p = cast(ubyte*) &q;
+        for (auto s = 0u, j = 0u; j < 4u; ++j)
+        {
+            auto b = 1u << (p[j] & 0x1fu);
+            if (s & b)
+                continue slide;
+            s |= b;
+        }
+
+        printf("%d\n", i);
+        break;
+    }
+}
+]]></highlight>
+
+The same but let Pygments guess the language:
+
+<highlight><![CDATA[
+import core.stdc.stdio : getchar, printf;
+
+extern(C) void main()
+{
+    slide: for (auto q = 0u, i = 1u; q & 0xffu ^ '\n'; ++i)
+    {
+        q <<= 8u;
+        q |= getchar();
+        if (i < 4)
+            continue;
+
+        auto p = cast(ubyte*) &q;
+        for (auto s = 0u, j = 0u; j < 4u; ++j)
+        {
+            auto b = 1u << (p[j] & 0x1fu);
+            if (s & b)
+                continue slide;
+            s |= b;
+        }
+
+        printf("%d\n", i);
+        break;
+    }
