So why not come up with a patch to the regular expression in Pod::Parser
so that neither one is required?

I'm the first one to say how much I dislike having that code inside
Pod::Parser to hack things up to allow -> and => in certain cases. I'm
also the first one to admit the overwhelmingly vast majority of p5p
was pretty insistent upon it at the time - which is why I coded it up
anyway, even though my own preference and instincts went against it.

Zoinks - I don't care for that at all. I think it is far more limiting and
restrictive than is necessary. Why not just try to be more precise about
the circumstances under which '>' does NOT terminate a C<...>. Maybe
its not enough to simply be '->' or '=>', perhaps we only want to allow
certain classes of characters to be to the left of '->' and '=>' and
maybe only a select few punctuation characters are in that set.

Thats a heckuva lot more accommodating and less restrictive than
forbidding most forms of nesting (something which I'm not willing to do
because Pod::Parser gets used for lots more stuff than just translation
and removing the nesting will break lots of code that I personally have
a stake in).
