Is there any way to get at the size of the original (uncompressed) file

bzcat2 <file> | wc, but with the size of the files I'm dealing with it
takes several minutes for this command to complete and I would really
like to be able to do it quicker then that.
I think it's impossible for stream compressors
It would have been possible if bzip2's implementation bothered to keep
that data in its output file (if it was a seekable destination, like
gzip or unix compress used to do as far as I remember).
But from looking at bzip2 lib's sources it looks like they aren't doing
it.
So my conclusion right now is "no".
