sense.

Unicode whitespace is defined as any of the following characters, and no other:

0009..000D    <control-0009>..<control-000D>
0020          SPACE
0085          <control-0085>
00A0          NO-BREAK SPACE
1680          OGHAM SPACE MARK
180E          MONGOLIAN VOWEL SEPARATOR
2000..200A    EN QUAD..HAIR SPACE
2028          LINE SEPARATOR
2029          PARAGRAPH SEPARATOR
202F          NARROW NO-BREAK SPACE
205F          MEDIUM MATHEMATICAL SPACE
3000          IDEOGRAPHIC SPACE

How straightforward would it be to allow the DMD compiler to accept /precisely/
this list as whitespace in a D source file?

Java got itself into a bit of a pickle by defining whitespace differently from
Unicode. They ended up having to have two separate functions (which from memory
I think are called isWhitespace() and isJavaWhitespace(), but I could be wrong).

It would be quite cool to have D whitespace and Unicode whitespace as one and
the same thing, don't you think?

PS. I /don't/ reccommend changing the value of const char[] whitespace; in
std.string, however. To do so would set an AWFUL precedent which const char
letters would NOT want to follow. You might, however, consider renaming those
constants to ASCII_WHITESPACE, ASCII_LETTERS, etc., once the new Unicode stuff
is up.

In Java:
Character.isSpace(char c)
 is deprecated and replaced by
Character.isWhiteSpace(char c)
Also
Character.isSpace(char ch)
for the Unicode space char.

There is no "isJavaWhitespace()" or
"Whitespace()"

There is Character.isJavaLetterOrDigit(char c) which
is deprecated, maybe you were confused with this.
