Question
Show why outermost evaluation is preferable to innermost for the purposes of evaluating the expression fst $(1+2,2+3)$.
Step 1
So we would evaluate $1+2$ and $2+3$ separately. $1+2$ would give us $3$ and $2+3$ would give us $5$. Then, we would substitute these values back into the original expression, giving us fst $(3,5)$. Show more…
