Yes, this is how they behave. The most important difference is that:
column ~ 'regex' (i.e., the operator)
can only accept embedded switches since there is no place to write a formal
flag like you can with the functions.
Though there is a case-insensitive operator as a usability feature the
other modes lack any external operator support.
