 In this case a view ´v´ is searched which is applicable to ´e´ and whose result contains a method ´m´ which is applicable to ´\mathit{args}´.

 The implicit view, if it is found, can accept its argument ´e´ as a call-by-value or as a call-by-name parameter.
 However, call-by-value implicits take precedence over call-by-name implicits.
