That is not comparable to removing const; const is not involved in
any decisions involving polymorphic dispatch. It does not provide
type inference.

In C++ it does, and so in C++ you cannot remove const from programs,
in general, without turning them into a mess that requires
a diagnostic.

Except in the case of storage that is actually unmodifiable, like
string literals, const *introduces* the error conditions which it helps
diagnose.

(Again, this is different from type declarations. Type declarations do not
introduce type; type is already there, and applying the wrong type of operation
on a value is already a bug.)

A program might contain an instance of an object being modified
unitentiontally, or surprisingly.

In a program that is free of const, this doesn't require a diagnostic.

It also, in and of itself, isn't an error at the language-construct level (it
isn't undefined behavior) though it may be a software defect: one which causes
the program to compute an incorrect result over correct inputs, and perhaps
invoke undefined behavior elsewhere.

The const qualifier can help catch some instances of unintended mutations.

It helps most with those objects or object members which can be marked
as not mutable by any code at all.

When const is fastidiously applied throughout a code base (it adheres to "const
correctness") then programmers are free to assume that if a function has a
"const type *x" parameter, then the function does not modify *x. And,
conversely, if the parameter is "type *x", there is a strong reason to
suspect that the funtion does modify *x; because otherwise, in keeping
with "const correctness", it would have been declared otherwise.

This can be helpful, because it is quite important to know which functions
parameters are pure, and which mutate. If the declaration, or a comment
next to it, do not answer the question, the programmer has to waste time
investigating this.
