+# This setup is a _specific_ example from Catalyst.
+
+# CAF _will not_ replace a pre-existing symbol, but there never
+# used to be a 'meta' symbol before CAF things are ported to Moose
+
+# Therefore, 'meta' needs to be treated as a special case, as
+# code which is _not_ using the symbol already should be allowed to
+# say $self->meta, and get all the Moose goodness, but code which
+# makes an accessor called ->meta should still work!
+
+# 22:22 <@groditi> the difference is meta wasnt there as a method before, but MooseX::Adopt::CAF does have a meta method.
+# 22:23 <@groditi> i guess i could namespace::clean it out. but it might create confusion
+# 22:23  * t0m nod - I think we need a special case for this..
+# 22:23 <@groditi> mst: thoughts?
+# 22:23 <@mst> Moose needs to not export 'meta' if you don't want it
+# 22:24 <@groditi> so namespace::clean it out or what?
+# 22:25 <@mst> hmm
+# 22:25 <@mst> does ->mk_accessors(qw(meta)) work if you do "use base qw(...)" instead of use Moose ?
+# 22:26 <@mst> if it doesn't, then it isn't a bug in CAF
+# 22:27 <@groditi> its my bug. because Adopt does use Moose because Emulate is a role
+# 22:27 <@groditi> so if you isa CAF then you definitely can(meta)
+# 22:27 <@t0m> I think that if the user makes an accessor called 'meta', we need to remove the Moose package symbol, and 
+#              immutable the class so the the accessor / constructor doesn't touch meta..
+# 22:27 <@t0m> and generate a warning.
+# 22:28 <@t0m> which is ugly as, but kinda works.
+# 22:29 <@groditi> ok ok. i'll do has_method
+# 22:29 <@t0m> as you want users who aren't shitting on the moose symbol to be able to call $self->meta as they 'Moosify'
+# 22:29 <@groditi> this sucks though because Emulate counts on meta being there
+# 22:30 <@groditi> ok well this requires major major changes so delayed until i finish finals
+
+# Suggested fix - something less hacky than:
