I really fully agree!
When working a few years back I had to trace through a piece of code
where the original author had done something like:

with My.Stuff.something do
  with My.Other.Stuff.somethingelse do
    with myyetanother do
    begin
      someproperty := xxx;
      ....
      ....
    end;
It was totally impossible to make sense of anything while debugging!

WITH should be abolished in my view!

I had to make local variables to shorten down the length of the
identifiers and then put the correct variable in front like:
  MS.someproperty := xxx;

Only then was it possible to inspect the values while debugging.

Further: I see every other day in the Embarcadero forum comments by
Remy Lebeau where he strongly advices against using WITH. Only goes to
show that it plagues Delphi as well.

Join the crusade against WITH!!!
