Yes, this is well known, and as Tuck says, all production
quality Ada lexers have known about this for two decades,
and handle it with no problem (apostrophe after identifier
is always a tic). Any lexer not able to do such computations
will have trouble. Note that if you are using a tool like
flex, there is absolutely no problem in dealing with this.
I do not know about open token.
