I think one way to solve the problems you describe in that URL is to
set a temporary breakpoint whose commands set the watchpoint:

   tb do_that
   commands
   > watch ptr->i
   > continue

(and similarly for block-local variables: put a breakpoint on the
block's first line).  If you want to keep the watchpoints between
sessions, record the temporary breakpoints and reinsert them when the
session starts.

Would this do what you want?
