Bug in last exercise of Partially Applied Functions

[genghis-yang]

It says "There was a problem evaluating your answer, please try again later." in the last exercise in Partially Applied Functions even when I can run it successfully in local Scala console.

It seems the operator "=>" was converted to a character '⇒' exceptionally.

I have submitted a PR #131 to fix it. Please check and merge it.

The Unicode form of "Rightwards Double Arrow" is a valid keyword. You can check it in spec. (https://scala-lang.org/files/archive/spec/2.12/01-lexical-syntax.html#identifiers)

The Unicode operators \u21D2 ‘⇒’ and \u2190 ‘←’, which have the ASCII equivalents => and <-, are also reserved.

The Unicode and ASCII versions can be used interchangeably.

scala> def fun(g: Int ⇒ Boolean) = ???
fun: (g: Int => Boolean)Nothing

scala> def fun(g: Int => Boolean) = ???
fun: (g: Int => Boolean)Nothing

Thanks for your explanation. I will close this issue.
