Hi,

thanks for the example. Unfortunately, I believe my problem is somewhat more
complicated. With your example, statements are all of the same type 
(except for
comments, but these are skipped anyway). I'd like to parse more general 
statements.
These may be specified in any order. I thought I could accomplish the 
'any order' thing
by using an abstract base type 'Statement' to derive specialized 
statements from.
By parsing statement blocks into std::vectors using something like

r_block %= *r_statement; // rule is declared to parse into 
std::vector<Statement>
r_statement = r_statementType0 | r_statementType1 | .. | r_statementTypeN;

I would like to retrieve a list of these statements. Problem is that I 
don't no how to
'BOOST_FUSION_ADAPT_STRUCT()/'/ the hierarchy.

Cheers, Stefan
