So basically you say, because of your reasoning, no one should be able to
use such a feature in there code?
It should do what is semantically natural for "const" -- namely,
prevent programmer from modifying the variable so declared.
Cf. "const Integer".
I understand that "const" meaning in Object Pascal has long
since lost it's meaning, but still, what it should *not* do
is breaking user programs unexpectedly
....

Also note that, implemented properly, removal of incref/decref calls
should not depend on any const declarations, it can be performed even
for non-const strings.

Differnet feature. Nice to have...

But no compiler can identify every occurrence where the ref count can be ommitted.

so it still stands:
What you want, is the removal of a feature from pascal. The feature for the programmer to explicitly skip the ref count (at the programmers own risk)

If that is the case: Should we remove "move" / "fillchar" too? Because they can do the same.
