Yes, on a correct re-reading, as prompted by you, I got it that "inaccessible" just meant directly inaccessible by its lexical-name (aka symbol) from the outside, not that the state of the lexical was inaccessible. I tend to go for as high a level of logical conceptualisation as can be managed, where accessibility of the "state" would be what primarily matters and once that established then dig into the nuts and bolts of mechanisms for it. Just my peculiar (not very perlish?) orientation!
