it - pannous/wasp GitHub Wiki

In lambda expression, the it keyword refers to the first (implicit) argument, otherwise it refers to self or the last result, which can be very ambivalent:

double:=it*2 # ok, implicit argument for function 'double'
double:it*2 # may interpret to anything later
double=it*2 # ok, [interpret](evaluation) immediately?

Todo: ambiguity?
