Some("abcdefg").get(3) //res0: Char = d
The argument to get() is sent to the apply() method of the String, but the source code for Option (and Some) doesn't have a get() method that takes parameters, and String has no get method at all.
So what get() is being invoked? Is it a mole from Java land?
It is StringOps.apply from implicit conversion
augmentString(Some("abcdefg").get)(3)
where augmentString is
@inline implicit def augmentString(x: String): StringOps = new StringOps(x)
Actually, in this case .get(x) is not a separate get() method but an abbreviation for .get.apply(x). So it's the standard get method on the Some type. No implicits required.
Some(Seq(99,32,12,7,101)).get(3) //res0: Int = 7
Many thanks to @Mario Galic for pointing me in the right direction.
