+* Llama — Compact syntax for short lambda
+
+This package implements the macro ~##~, which provides compact
+syntax for short ~lambda~, without actually being new syntax,
+which would be difficult to get merged into Emacs.  Past attempts
+to add syntax were met with determined pushback and the use of a
+macro was suggested as an alternative.
+
+The ~##~ macro, whose signature is ~(## FN &rest BODY)~, expands
+to a ~lambda~ expression, which wraps around these arguments.
+
+This ~lambda~ expression calls the function FN with arguments
+BODY and returns its value.  Its own arguments are derived from
+symbols found in BODY.
+
+Each symbol from ~%1~ through ~%9~, which appears in BODY,
+specifies an argument.  Each symbol from ~&1~ through ~&9~, which
+appears in BODY, specifies an optional argument.  All arguments
+following an optional argument have to be optional as well, thus
+their names have to begin with ~&~.  Symbol ~&*~ specifies extra
+(~&rest~) arguments.
+
+Instead of ~%1~, the shorthand ~%~ can be used; but that should
+only be done if it is the only argument, and using both ~%1~ and
+~%~ is not allowed.  Likewise ~&~ can be substituted for ~&1~.
+
+Instead of:
+
+#+begin_src emacs-lisp
+  (lambda (a _ &optional c &rest d)
+    (foo a (bar c) d))
+#+end_src
+
+you can use this macro and write:
+
+#+begin_src emacs-lisp
+  (##foo %1 (bar &3) &*)
+#+end_src
+
+which expands to:
+
+#+begin_src emacs-lisp
+  (lambda (%1 &optional _&2 &3 &rest &*)
+    (foo %1 (bar &3) &*))
+#+end_src
+
+Unused trailing arguments and mandatory unused arguments at the
+border between mandatory and optional arguments are also supported:
+
+#+begin_src emacs-lisp
+  (##list %1 _%3 &5 _&6)
+#+end_src
+
+becomes:
+
+#+begin_src emacs-lisp
+  (lambda (%1 _%2 _%3 &optional _&4 &5 _&6)
+    (list %1 &5))
+#+end_src
+
+Note how ~_%3~ and ~_&6~ are removed from the body, because their
+names begin with an underscore.  Also note that ~_&4~ is optional,
+unlike the explicitly specified ~_%3~.

+omitting the whitespace between it and the following symbol.
