$prop

Returns the property of a custom alias.

$prop

• This function has no parameters.

Example

alias value {
  if ($isid && $1 isnum) {
    if (!$prop) return $1
    elseif ($prop == squared) return $calc($1 ^ 2)
    elseif ($prop == sqrt) return $calc($1 ^ 0.5)
  }
return 0
}

In the above custom identifier, calling $value(2).square would return 4, $value(16).sqrt would return 4 and $value(3.14) would return 3.14
