It changed at the last hackathon, but is still being debated, mostly
on #perl6. The current S02 "early dot" rule is likely being abandoned,
but we don't know for what yet. The reason is that term/operator
lexer state is interacting badly with inconsistent retroactive
whitespace cancellation.

Sure, that one might be obvious, but quick, tell me what these mean:
say .bar
say .()
say .1
when .bar
when .()
when .1
foo .bar
foo .()
foo .1
.foo .bar
.foo .()
.foo .1
I'd rather have a rule you don't have to think about so hard. To me
that implies something simple that let's you put whitespace *into*
a postfix without violating the "postfixes don't take preceding
whitespace" rule.
