Thanks, I should have seen that one in the manual. Posting at the end of a
work day is
obviously not a good idea :-) I've got another lambda related question
though. My example was
a useless simplification, what I'm really trying to do is to read data from
an STL vector into a legacy
matrix class which doesn't have an iterator.

for_each( raster.begin(),
raster.end(),
( var( out2( h - 1 - c / w, c % w ) ) = _1,
++var( c )
)
);
