I thought it's a beauty contest.

```d
string stripsemicolons(string s)
{
   string result;
   // prevent reallocations
   result.length = s.length;
   result.length = 0;

   //append to string only when needed
   size_t i = 0;
   while (i < s.length)
   {
     size_t j = i;
     while (i < s.length && s[i] != ';')
       ++i;
     result ~= s[j..i];
   }
}
```
