digitalmars.D.learn - Build your own Trie entry table

Hello

I want to map a dchar to its Bidi_Class.

I've built an utility that reads UnicodeData.txt into an AA and 
builds a trie with std.uni.codepointTrie from it.
I use Trie.store() to export the trie entry table into a D 
module. (I believe in a similar manner than phobos' 
unicode_tables.d)

Now I want to use this table to efficiently create a Trie in my 
code, the same way std.uni does, but found out that Trie 
constructor is private.

I've copy-pasted the asTrie function (and also TrieEntry struct) 
in my code and it works well (which I don't understand because my 
code still ends up calling the private ctor).

Can you give indication on the workflow one should follow for 
this use case?

Thanks

This must be an oversight on my part. Indeed it should be 
possible to store/load your own trie.

Please file a bug report for Phobos basically stating your use 
case and the visibility problem.

 Thanks
