This is covered in the virtual row guide:
http://sequel.jeremyevans.net/rdoc/files/doc/virtual_rows_rdoc.html . You
pass an argument to the block and use the argument, instead of relying on
instance_exec:
Artist.where{|o| o.age > age_method}
It's good to review Sequel's documentation, as it is reasonably
comprehensive: http://sequel.jeremyevans.net/documentation.html . I
realize that doing so requires a significant time commitment.
Thanks,
Jeremy
