Just to make another argument about this.

Suppose you have

    (setf (logical-pathname-translations "FOO")
       `(("**;*.*" "/usr/foo/*.*")))

    (setf (logical-pathname-translations "GNAO")
       `(("**;*.*" "/usr/foo/*.*")))

The above is legal CL.  Now you do

   (translate-logical-pathname "FOO:qwe;rty.c")
    ==> #p"/usr/foo/rty.c"

   (translate-logical-pathname "GNAO:qwe;rty.c")
    ==> #p"/usr/foo/rty.c"

The question now is: what should the hypothetical

	(get-logical-pathname-from-namestring "/usr/foo/rty.c")

return?

Note that there are ways in CL to build a function that would return 
all the possible logical pathnames from an arbitrary pathname 
namestring.  This involves keeping track of all the defined logical 
hosts and building a match with all possible translations.

This is left as an easy exercise to the reader :)

Jokes apart, what are you trying to do?

Cheers
