Looks good. The ECLASS variable is specified by PMS, so it's a good idea to use a different name.

However, I am not able to reproduce the "invalid indirect expansion" message with bash-5.0. Maybe it's only triggered by your installed instance of 5.0_alpha::local-repo.

    inherit: use local -x ECLASS (bug 676014)
    
    Use local -x ECLASS, and also make __export_funcs_var a local variable,
    since this is simpler than managing these variables as globals
    (eliminates PECLASS and prev_export_funcs_var variables). As an
    additional benefit, this prevents interference from ebuild variables
    as reported in bug 656354 for the ECLASS variable.
