Precisely, you worry less because there are automatic, built-in ways to dec=
ect problems.
Of course (it is in any language) you need to do some mental calculation fo=
r choosing the right integer types. That's another story.

> How much of your effort goes into manual memory management?

You are assuming Ada forces you into manual memory management.
In Ada you can use most objects on stack (this includes unconstrained types=
); for those that need dynamic resizing you can use Vector's and other cont=
ainers using controlled types that do deterministic garbage collection.
I do entire applications with UI, data management & number-crunching withou=
t using any "access", "new" and "Unchecked_Deallocation".

Sure, it is called Ada 2005, Ada 2012 :-)
I'm afraid you are confused about what Ada really is because don't code eno=
ugh in it...
