Breaking backward-compatibility is unreasonable and unnecessary.

This would break backward-compatibility as well, as the /\p{Katakana}/s example showed.

By "non-Unicode implementations" are you referring to other regexp engines that don't support Unicode? If such beasts exist, is it our desire to be compatible with them?

It is confusing to raise a SyntaxError when the encoding of a regexp changes implicitly. This needs fixing either by ignoring property case for Unicode properties regardless of the regexp's encoding, or making all property names case-insensitive.

My understanding is the same, and the patch works:

  run@paint-desk:~/mir/ruby$ patch <reg.patch 
  patching file regenc.c
  ...
  run@paint-desk:~/mir/ruby$ irb
  >> /\p{AlNUm}/  #=> /p{AlNUm}/
  >> /\p{AlNUm}/n #=> /p{AlNUm}/n
  >> /\p{AlNUM}/n #=> /p{AlNUM}/n
