The is "name" in ngx_http_core_module location config, but note 
that it's not always a path - there are named and/or regexp 
locations.

E.g., the proxy module does this during configuration merge to 
later use the location path in internal operations:

    clcf = ngx_http_conf_get_module_loc_conf(cf, ngx_http_core_module);

    ...

    plcf->location = clcf->name;

    if (clcf->named
#if (NGX_PCRE)
        || clcf->regex
#endif
        || clcf->noname)
    {
        if (plcf->vars.uri.len) {
            ngx_conf_log_error(NGX_LOG_EMERG, cf, 0,
                               "\"proxy_pass\" cannot have URI part in "
                               "location given by regular expression, "
                               "or inside named location, "
                               "or inside \"if\" statement, "
                               "or inside \"limit_except\" block");
            return NGX_CONF_ERROR;
        }

        plcf->location.len = 0;
    }

See http/modules/ngx_http_proxy_module.c for all the code.
