How can you be sure that each of those alias types occurs only
once ?
The NameAliases.txt doesn't say anything about this, AFAIK:
http://www.unicode.org/Public/UNIDATA/NameAliases.txt
Also, what would name() return in case to alias of a particular
type is defined ?
I think it would be easier and more future proof to have a function
aliases(code) -> [(type, alias),...] which simply returns all
defined aliases. Applications could then add helpers for
select the type they would like to use.
It may make sense to also add the name(code) value as
e.g. ('standard', name(code)) to that list.
