I went to archives and read the whole discussion for this from the beginning
I did not really understand, why using the ALIAS FOR syntax is significantly harder to implement then #routine_label The things you mentioned as currently using #OPTION seem to be in a different category from the aliases and block labels - they are more like pragmas - so to me it still feels inconsistent to use #routine_label for renaming the outer namespace. Also checked code and indeed there is support for #OPTION DUMP and #VARIABLE_CONFLICT ERROR Is it documented and just hard to find ?
