The program was compiled despite the fact that it contains an error #12

I tried to run programm

function sum (id, pr, n, a): l := id n / pr r := (id + 1) n / pr s := 0 for i := l until r: s += a[i] send(0, s)

if id == 0:
    ans := 0
    for i := 0 until pr:
        ans += recieve(i)
    print(ans)

It contains a mistake: recieve instead of receive. But I did not receive a message about CE. Instead of this I receive very strange message:

Please check out the issue#6 you’re trying to duplicate. If you open the file (runner.d) near the given line (206), you will find out that the error pops up in case the function name cannot be recognised. So the issue is not in receiving CE itself, but in non user-friendly text.

There are actually two distinct issues here.

  1. cryptic message, same as #6
  2. the fact that the error is not triggered at compile time
