--- Comment #6 from Rae Kim <rae.kim at gmail dot com> ---

When "info variables foo_map" is executed returned type string doesn't have
"class "

> (gdb) info variables foo_map
> All variables matching regular expression "foo_map":
> 
> File main.c:
> 4:      std::map<int, int, std::less<int>, std::allocator<std::pair<int const, int> > > foo_map;

Language is changed to the m_language of the symbol during "info variables
foo_map".
(scoped_switch_to_sym_language_if_auto l (sym))

symtab.c:
> 4883    static void
> 4884    print_symbol_info (enum search_domain kind,
> 4885                       struct symbol *sym,
> 4886                       int block, const char *last)
> 4887    {
> 4888      scoped_switch_to_sym_language_if_auto l (sym);
> 4889      struct symtab *s = symbol_symtab (sym);
> 4890
> 4891      if (last != NULL)
> 4892        {

Is it possible to apply something like "scoped_switch_to_sym_language_if_auto"
to pretty print?
