The eqivalent do in C:

Brent and Tony have already given the closest Haskell equivalents.

For completeness, it's worth pointing out that the above C is equivalent to

void doBlock() {
    if (some preCondition) {
      return;
    } else {
    ...
    }
}

So you can write it similarly in Haskell using if/then/else.
