How about using Haskell Server Pages[1] and get both?

doc = <b><i><% v1 %></i><% v2 %></b>
      v1 = "<>"
      v2 = "test"

No more error-prone than apfelmus' embedded language (it *is* an
embedded language), and no more complex to write than the SafeString
example (less in fact). And a lot more enjoyable than Ruby (ok, I
admit, that's not an objective statement).
