Passing nameless argument to function requiring an implicit named argument fails

[BSteffaniak]

public trimEnd(var Int: end = count - 1, Char[] charsToTrim = WHITESPACE) -> String {
  while (end >= 0 && charsToTrim.contains(chars[end])) end--

  return end < 0 ? "" : substring(0, end + 1)
}

public trimEnd(Char charToTrim, var Int: end = count - 1) =>
  trimEnd(end, [charToTrim])

passes [charToTrim] as generated54: [charToTrim]

A workaround is to call the function like this: trimEnd(end, charsToTrim: [charToTrim])
