From Info
-- Function: overlay-get overlay prop
This function returns the value of property PROP recorded in
OVERLAY, if any. If OVERLAY does not record any value for that
property, but it does have a `category' property which is a
symbol, that symbol's PROP property is used. Otherwise, the value
is `nil'.
If 'category where allowed to be a symbol then buffer local values could
be set.

`category' is already a symbol. I presume you're saying, "if the user
were able to specify a custom forwarding symbol to use instead of
`category', then ..."
I'm not sure it's a good idea though, as in many cases overlay lookups
are implicit, so there's no easy/clean way to specify what symbol to use
(instead of `category').

Sorry, I meant "to be a variable containing a symbol". Would that be any
problem?
