+/* FIXME: carlton/2003-09-25: This next bit leads to lots of
+ reduce-reduce conflicts, because the parser doesn't know whether or
+ not to use qualified_name or qualified_type: the rules are
+ identical. If the parser is parsing 'A::B::x', then, when it sees
+ the second '::', it knows that the expression to the left of it has
+ to be a type, so it uses qualified_type. But if it is parsing just
+ 'A::B', then it doesn't have any way of knowing which rule to use,
+ so there's a reduce-reduce conflict; it picks qualified_name, since
+ that occurs earlier in this file than qualified_type.
+
+ There's no good way to fix this with the grammar as it stands; as
+ far as I can tell, some of the problems arise from ambiguities that
+ GDB introduces ('start' can be either an expression or a type), but
+ some of it is inherent to the nature of C++ (you want to treat the
+ input "(FOO)" fairly differently depending on whether FOO is an
+ expression or a type, and if FOO is a complex expression, this can
+ be hard to determine at the right time). Fortunately, it works
+ pretty well in most cases. For example, if you do 'ptype A::B',
+ where A::B is a nested type, then the parser will mistakenly
+ misidentify it as an expression; but evaluate_subexp will get
+ called with 'noside' set to EVAL_AVOID_SIDE_EFFECTS, and everything
+ will work out anyways. But there are situations where the parser
+ will get confused: the most common one that I've run into is when
+ you want to do
+
+ print *((A::B *) x)"
+
+ where the parser doesn't realize that A::B has to be a type until
+ it hits the first right paren, at which point it's too late. (The
+ workaround is to type "print *(('A::B' *) x)" instead.) (And
+ another solution is to fix our symbol-handling code so that the
+ user never wants to type something like that in the first place,
+ because we get all the types right without the user's help!)
+
+ Perhaps we could fix this by making the lexer smarter. Some of
+ this functionality used to be in the lexer, but in a way that
+ worked even less well than the current solution: that attempt
+ involved having the parser sometimes handle '::' and having the
+ lexer sometimes handle it, and without a clear division of
+ responsibility, it quickly degenerated into a big mess. Probably
+ the eventual correct solution will give more of a role to the lexer
+ (ideally via code that is shared between the lexer and
+ decode_line_1), but I'm not holding my breath waiting for somebody
+ to get around to cleaning this up... */
