[parenscript-devel] top-level LET and LET* will not create global variables

[Daniel Gackle]

Hi Yakov,

Yes, that does look inconsistent with the documentation. I use DEFPARAMETER
if I need such a variable.

Perhaps that line of documentation dates from before Vladimir implemented
lexical scoping.

By the way, Vladimir is traveling for a few months and most changes will
probably have to wait until he is back.

Daniel
