Also look into proto::functional::unpack_expr, <snip>
OK, I like the idea. I tried to get it working but I stumple against the fatc that proto make_expr takes push_front() as a Sequence and don't try to evaulate it before hand, leading to a "no size for psuh_front" erro in fusion. I'll try to get this sorted though.
My main question is that, when and when not a transform call get evaluated ? Like if i do foo( bar ( _) )
is bar(_) evaluated before being evaluated by foo ? Sometimes it seems it does and sometimes no :/
You'll have to post your code ... I can't tell what problem you might be running into. -- Eric Niebler BoostPro Computing http://www.boostpro.com
