Speaking of confusion, I'm not sure if I agree with the names you
specify, so perhaps I am confused. Here are the three ways that I can
see to call a function:
#1 do MyFunct(MyVar) <-- pass by value
#2 do MyFunct(.MyVar) <-- pass by reference
#3 do MyFunct("MyVar") <-- pass by name
It seems that you are naming method #2 "call by name"
