I don't think we have enough ways of doing the same thing yet...

so here's one more..

"abc;def;ghi".substitute(";", "");

Using libraries can trigger hidden allocations.

```
import std.stdio;

string garbagefountain(string s){
    if (s.length == 1) return s == ";" ? "" : s;
    return garbagefountain(s[0..$/2]) ~ 
garbagefountain(s[$/2..$]);
}

int main() {
    writeln(garbagefountain("abc;def;ab"));
    return 0;
}

```
