No, I was talking about the substitution, that the principle is about.
 
It's not about substituting types, such as substituting types in the C++
declaration of an object.
 
That was very clear the way I wrote it, but not after you successfully
trollingly quoted out of context and in new context, part of the
paragraph (indeed part of a sentence), where you sniupped that which
could inform a reader that your new context was misleading.

No, you trolled.
 
That involves a fair bit of misdirection.

Again LSP is about types not objects; objects do not define behaviours
types do. The object substitutability you speak of only applies to
objects of related types and it is the behaviours as defined by those
types that is important not the objects themselves.

Yes, I was referring to identifiers in my last message - indeed an extra
layer or a smart editor could do.
