Yes, that is the intention. If there are different language variants
that have different keywords or when certain DWARF constructs can be
interpreted differently depending on the version used in the source. For
C++11 there certainly is a usage.

But C++03 does not change the language in any way from C++98 represented
by DW_LANG_c_plus_plus. It really isn't a different language variant,
just some library extensions (and the library will be described by
existing DWARF constructs already). So the question is whether the
proposed DW_LANG_c_plus_plus_03 constant is actually needed, and if
adopted by DWARFv5, how a producer and consumer need to interpret it.

Cheers,

Mark
