Did you know that " %{ .... }" is a string literal in ruby?

By using this, from the users point of view the only different to passing a
"real" block, instead of a string, would be that he has to write a "%"
before the curly brace. (and this it would act like a closure, e.g. giving
you access to the surrounding variables).
