I've written a regular expression EvalFunc similar to ExtractAll except
this is called FindAll.  It returns a tuple of all strings found that
match the given pattern.  The syntax looks like this:

A = FOREACH raw_data GENERATE FindAll(field_str, '[^/]+') AS a_tuple;

I dumped some return tuples which look something like this:

((a,b,c,d,e))

I'm trying to get the size of the tuple so I can filter out certain
entries.  If I simply do:

B = FOREACH A GENERATE SIZE(a_tuple);
DUMP B;

I always get a size of 1.  I thought maybe this was due to the
surrounding bag so I tried to FLATTEN(FindAll(...)).  Now I'm getting an
error from SIZE saying it can't convert a string to a DataBag.

Any idea what's going on here?

Thanks,
