+0000000: javac needs to support library development for non-Java langauges
+Summary: token syntax (currently non-standard) for introducing exotic identifiers
+
+http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=<TBD>
+
+Features:
+- hash mark followed immediately by string literal creates an identifier of the given spelling
+- no other processing or interpretation is given to the identifier
+- #"foo" is indistinguishable from foo, if foo is a normal, non-keyword identifier
+- BUG: the javac backend needs to check exotic identifiers against JVM limitations
+- user must mangle invalid symbols; see http://blogs.sun.com/jrose/entry/symbolic_freedom_in_the_vm
+
+Examples from the unit test:
+ class #"*86" {
+ String #"555-1212"() { return "[*86.555-1212]"; }
+ }
+ class #"int" extends Number {
+ final int #"int";
+ #"int"(int #"int") {
+ this.#"int" = #"int";
+ }
+ static #"int" valueOf(int #"int") {
+ return new #"int"(#"int");
+ }
+ public int intValue() { return #"int"; }
+ public long longValue() { return #"int"; }
+ public float floatValue() { return #"int"; }
+ public double doubleValue() { return #"int"; }
+ public String toString() { return String.valueOf(#"int"); }
+ }
+
+Authors:
+- John Rose (Sun)
+
+Tests:
+- unit test test/tools/javac/QuotedIdent.java
+
+Incremental testing:
+This does not require a full JDK build.
+
+$ cd .../langtools
+$ hg qpush quid.txt
+$ (cd make; make)
+$ ./dist/bootstrap/bin/javac -d dist test/tools/javac/QuotedIdent.java
+$ java -version # should print 1.6 or later
+$ java -cp dist QuotedIdent # should print OK
