Thanks Konrad,
I already have a lot of custom directives, but what I was wondering is if
there's a way to make them both implicit.
Maybe this is a more general scala question, like: how can I make all the
parameters of a lambda implicit, because "{ implicit x=> ... }" works while
"{ implicit (x,y) => ...}" doesn't .
Cheers
G
