If I understand you (which I very well may not :), you are asking if you can
execute a block in the context of the method you send the block into.

Check out html/common.rb (comes standard with Ruby) which has html
generation code.  In the middle of HTML.def_element you'll see:

              buf = instance_eval(&block)

It's that simple.

(Mind you, it took me quite a while to figure out why my #$*!ing blocks
weren't working properly!  When I found out what was going on, I stopped
using this library and wrote a quick-n-dirty one of my own.  Now I just
subclass.)
