[Openmcl-devel] symbol garbage from Hemlock typing

[Ron Garret]

This is a known bug:

http://trac.clozure.com/ccl/ticket/1246

A workaround:

; Temporary (I hope!) bug fix
(defun case-insensitive-string-to-symbol (&rest args)
  (declare (ignore args))
  nil)

This will not be a problem when you just read in a file or copy paste but it will produce tons of unwanted symbols that will confuse various tools such as symbol completion.
