Eep. I thought I had mutt's utf-8 working, but apparently not.
Does anyone who knows about these things want to mail me instructions,
or something? That'd be nice

Well, almost. Now this would be lisp-y:

So I sit here and think for a minute about how nice it will be in P6 to
be able to define
operator infix:eqi($str1, $str2) {...}
for doing
if ($1 eqi last)
and I think about the whole 'C' string library. Which dredges up my old
questions about parameterized operators:
How can I

If it's one of the 'base' binary operators (addition, subtraction, and
whatnot) you don't.

I see a few possibilities. The first, call it like a function:
if infix:eqn(Dough, Douglas, n = 4) {...}
Or, you could use the adverbial modifier Cwhere (well, not officially

I wonder if the . operator is available here:
if Dough eq.n(4) Douglas { ... }
that makes it intuitive how to define new equality methods. One thing of
concern is that we'd need whitespace rules to disambiguate things. I
