I'm no SGML historian, not even close, but most languages do not allow
certain characters in their keywords and identifiers and they don't
allow them to be escaped either.
public class Quoted"Strange" {}
could be escaped as:
public class Quoted"Strange" {}
or:
public class Quoted\"Strange\" {}
.....
Point being: having identifiers not being escapable makes sense to me. I
have always found it a bit unfortunate that more and more languages
allow higher characters (above the US-ASCII range) to be used in
identifiers, including XML, which begs for compatibility problems (I've
opened German PHP sources in a text editor which showed the names of
identifiers and text crippled because PHP does not have a clear way of
stating the encoding).
Yet I can also understand the pints of the internationalization lobby...
(using Chinese in your identifiers perhaps makes sense when you're from
China, but don't expect everybody to be able to read your and understand
your code)
