Which it is, in a way.
Still, I don't think ^ as a sigil needs to mean the same thing as ^ as a
twigil. Visually similar pairs are also not related:
?foo $?foo
*foo $*foo
+foo $+foo
=foo $=foo
<foo ...> $<foo
I think that it would help, and in different ways, even, to see ยข as a
prefix operator with special syntax, instead of as a sigil. It doesn't
fit well in the list of sub, hash, array, scalar.
Making it a prefix op would allow whitespace after it, which would make
the "class" keyword not seem so desperato. (I think it's a bad keyword
for this, and picking ^ instead would render it unnecessary, but more
about why I think "class" is bad for this in a later post.)

Is this the same "conflict" that occurs in %foo % %bar?
(I cannot imagine needing a one() junction for types, by the way. If
someone can come up with a good real-life example, please do so.)
