Hi,
In following code:

object TheApp {
  
  def main(args : Array[String]) {
    implicit val innocentMap = Map("foo" -> Set("bar"))
    "baz".nonEmpty
  }
  
}
instead of computing expected true as "baz" string is non empty
results in "java.util.NoSuchElementException: key not found: baz"
I tested it on 2.10, 2.11.8, 2.12.RC2 with same results.
The implicit innocentMap is the culprit.
After decompiling "baz".nonEmpty looks like this:
((TraversableOnce)innocentMap.apply("baz")).nonEmpty();

Can anyone tell me why innocentMap.apply is magically called here?
Highly unexpected behaviour. If innocentMap has different type like:
implicit val innocentMap = Map("foo" -> ("bar"))
code behaves as expected.

Sholud I report scala library bug?
