My latest dream was related to some good knowledge i had with arithmetic operators (+, -, *, /, **, %, &&, !, ||, ^^, &, !, |, ^, =, !=, :=, >, >=, <, <=, = [,], != [,], = (,), != (,), = [,), != [,), = (,], != (,] ) thanks to the MUGEN engine where i was studying the expression documents (2001 ver).
