Dear all,
The spec at https://go.dev/ref/spec#For_range says
"The range expression x is evaluated once before beginning the loop, with
one exception: if at most one iteration variable is present and len(x) is
constant, the range expression is not evaluated."
What does the second half of this sentence mean?
My guess was that this says that in "for i := range [3]int{1, 2, f()} ..."
the function f is not called, but I quick experiment shows that this guess
is wrong, see https://go.dev/play/p/MXqH_C7mllx .
All the best,
Jochen
