 Well, yes, but if you have a longish string and more than two-three values = to fill, it can be difficult to see what value goes where and what the resu= lting string will look like.

In some si= tuations string interpolations are cleaner, in others printf-like formattin= g is more readable... it can really go both ways. *In general* I prefer pri= ntf-like formatting tho.

There's an argument f= or supporting both in that reguard.
