Yes, it is a strength. You may want a new control operator. In case of, say, Java, you go and ask language developers. In case of Haskell, you write a function or a bunch of functions. "if-then-else" can be implemented in Haskell as a function, for one example. Myself, I created a lot of these control operators when I worked with Haskell. I also used a lot of operators defined by others.
