Scala Call By Name Confusion

Question

I am working on some call by name examples using the REPL and running the same examples in Eclipse.

Here is what in Eclipse:
Scenario 1:

val fun         


        

Answer 1

Scenario 1: As expected. The output is from the first line, not calling the method.

Scenario 2: I don't have Eclipse, but doesn't sound right.

REPL Scenario 1: you can't define a call by name value. what you did is assign the last value of the expression {println("Calling funct")} to funct. That last value is the result of println, which is Unit. So takesFunct receives a thunk that evaluates to just Unit, so nothing is printed.

REPL Scenario 2: As expected
