I guess that my point was that for the situations where the built in syntax in OO languages is used, the lens alternative is usually at most about 2 characters longer, which is hardly more inconvenient.

That's a point, just one that was entirely missing from your previous comment.

That said, it's not just use. You've also gotta deal with some additional imports, and with defining your lenses. For the simplest case, that's a bit of overhead compared to having it all baked in.
