+	* parser.l: Syntactic tweak. Do not allow the "extra"
+	constituent chars # or ^ to start the symbol name after an @.
+	Prior to this change @^a is a "meta-symbol" whose name is "^a",
+	but ^a is the ^ quasiquote notation followed by symbol a.
+	After this change @^a is meta, applied to quasiquote-a.

 	* lib.c (lazy_sub_str): Bugfix: "from" was mistakenly used
 	in the adjustment of the "to" value.
