repeat

Flag while (TRUE), an unconditional loop better written as repeat.

repeat states the intent — loop until a break/return — without the dummy TRUE condition. Only the reserved literal TRUE is matched; the rebindable T is left to true-false-symbol.

An unconditional while loop:

while (TRUE) {
  poll()
}

  | ^^^^^^^^^^^^ `while (TRUE)` is an unconditional loop; use `repeat`
  = help: Write `repeat` for a loop with no exit condition.

After applying the fix:

repeat {
  poll()
}
