Why is there a difference in the behavior?

Your first assert expression is looking for a string in a larger string, your second expression looks for hay which is not a string but a string[]. To flatten the array, use:

assert(canFind(hay.join, "111"));

This succeeds.

assert(canFind(hay, "aaa222aaa"));

So the difference in the behaviour is caused by canFind checking for equality when string[] is passed. Is this the expected behaviour? I wouldn't want to join the array, for the array could be really big.
