call by reference

Yes, use a value that you can modify destructively.

void foo(mapping m) { m->s=m->s+"!"; }

void main() { mapping m=(["s":"Hello World"]); foo(m); write(m->s+"\n"); }

I was under the impression that call by reference was default in pike, but it seems I've lived a lie. Is there a way to write

void foo(string s) { s=s+"!"; }

void main() { string a = "Hello World"; foo(a); write(a+"\n"); }

without returning a string from foo?
