You beat me on this one :)  That's something I wanted, not only for
factorization, but also because I think this is a service which define
should provide, so that in macros we don't have to ifelse errprint etc.
which would slow down things too much.

I would also like to have the location site attached to the values too,
and ultimately have m4 provide M4sugar's expansion_stack which allows
to know the expansion track that was followed until some failure/warning
message.

Really, a gareat patch :)
