(note: snipped [beeped!] some inflammatory passages... <g>)
atomicised operations focused on handling errors close to the source
of error (for specific handling) can do with a lower degree of
nesting. i.e.

try   op1 finally   cleanup / error handle op1 end;
try   op2 finally   cleanup / error handle op2 end;
.....
try   opN finally   cleanup / error handle opN end;
we discussed this approach before.

Surely, I've just not looked into that (performance not being my primary
argument against exception driven error handling).
