Does anyone know when lexical scope started appearing in Lisp?  Not
counting Scheme, did it exist in predecessors of Common Lisp?  Was it
used much?  Is it really true that Common Lisp had both lexical and
dynamic scope in order to support older code that was written relying on
dynamic scope and was too hard to convert?

Thanks.  This topic came up in the Forth group.
