I probably wouldn't use that. That wasn't what it was intended 
for and it's not really UFCS. It's was meant for properties that 
are defined as functions.

struct SomeStruct
{
     void foo(int);
}

SomeStruct s;
s.foo = 10;

It's kind of horrible syntax for what it is doing, where it isn't 
obvious what is happening. Writeln and iota aren't setting 
anything, they are just function calls that happen to be able to 
take one parameter.
