With UFCS it looks a lot nicer already:
foo(i"My name is $name".text);
How often do you actually need to pass an interpolated string to 
a function in string form? That's not a rethorical question, it 
is important to consider. If 90% of string interpolation happens 
in writeln / logging then it's not worth forcing the use of 
phobos + GC + eager toString and concatenation just to make the 
remaining 10% of cases a bit easier.
