Demangling v0 is already supported by the latest releases of binutils
(2.36) / gdb (10.2), e.g.:

echo _RNvXNtCshGpAVYOtgW1_7example9my_moduleINtB2_13MyGenericTypeNtB2_6MyTypeENtB2_7MyTrait9my_method
| c++filt -i
<example::my_module::MyGenericType<example::my_module::MyType> as
example::my_module::MyTrait>::my_method

See the current status at https://github.com/rust-lang/rust/issues/60705.

(which reminds me I have to update the "Hacking" section in the Quick
Start guide, because now the releases I backported the support into
are not needed anymore)

Cheers,
Miguel
