Introduction

Method overloading sucks in Scala because it detracts from your flexibility. An implicit conversion is a feature of Scala that let's the compiler look up how to convert objects between types at compile time.

Let's say I define a method with the following signature:

def doSomething( action: Action )

Somewhere else in the code I write:

##motions

motion	description
h	Count characters left
l	Count characters right
^	To the first character of the line
$	To the last character of the line
f<char>	To the counth character occurrence to the right. F<char> to the counth character occurrence to the left
t<char>	To 1 character just before the counth character occurrence to the right
T<char>	To 1 character just before the counth character occurrence to the left
