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.
Actually, canFind documentation is perfect.

assert( canFind!((string a, string b) => a.startsWith(b))(words,
"bees"));
Thanks for the help anyways!
