There are plugin callbacks which trigger at the end of processing types
and C++ functions,
but I can not find a clean way for plugin code to notice a top-level
variable declaration.
I'm hoping that the answer does not require the plugin shared library to
bind to global symbols of the compiler (i.e. global_namespace).
TIA - Terrence Miller

Why not? That's what dehydra does: it enumerates through the items in
global_namespace in PLUGIN_FINISH_UNIT.

Because it makes the name "global_namespace" and the list
order(TREE_CHAIN (t) points to a declaration
located earlier in the file than t) be part of the plugin interface and
these two items are not documented. Also
you end up with one way of handling top-level types (PLUGIN_FINISH_TYPE)
and functions
(PLUGIN_CXX_CP_PRE_GENERICIZE) and a different way of handling
variables. A better scheme (IMO)
would be to have a plugin triggered when the declaration of a variable
is complete and another pair of plugins
for scope entry/exit.
