Encode Hackers,
I have found a big bug in alias implementation; you can't override
alias later on!
Suppose there is a user who wants to use vendor encoding. S/he may
Encode::define_alias( qr/sjis$/i => '"cp932"'); # Windoze or die!
But you will still get shiftjis.
I checked the code and found that it is harder you may think, because
we allow regexes and coderefs to alias. But I think I have come up with
a solution. Very fortunately, regexes can be hash keys and we can even
resort to use Tie::RefHash for coderef so it is theoretically possible
to remove duplicates (currently aliases are pushed in an array so
duplicates are possible. I believe this is a coderef concern). We
still need an array to preserve order (or Tie::IxHash? But it is not
included in the current perl dist) but the point is we have to find some
way to override/overwrite alias settings....
