I'm not an expert on these tools, so maybe this is a
silly message, but the recently posted Ada Yacc/lex stuff
leaves me puzzled.
Just a couple of points
(a) I don't see how it handles the substitute characters
(b) It seems to allow adjacent underscores in numbers and
identifiers, and even leading underscores in identifiers
(c) I can't see how it distinguishes attributes from character
literals - consider for instance "F()'FIRST", or worse,
"F()'X'FIRST", where 'X is an implementation-defined attribute
Can anyone help?
