+"This package provides a concise, intuitive and flexible macro for trivial
+lambdas that eschews explicit  naming of parameter variables in favor of
+positional references, with support for a used or ignored &rest parameter
+and automatic declaration of ignored parameters when logical @code{gaps}
+are left in the positional references.  Further convenience features
+are provided.")
