Thanks, Yaroslav. I forgot about that one, which is odd since IIRC it's me who
pressed Sam Steingold to explicitly mention this is the CLISP impnotes.
-- Blush.
Still I don't appreciate interfaces that need unwind-protect etc. or special
variables to work. I very much prefer functional APIs. The other ones get
scoping typically wrong. Consider th effect of
(ext:letf ((custom:*foreign-encoding* charset:utf-16))
(convert-some-string)
(foreign-funcall some-function-which calls back into Lisp))
Within the extent of the callback, the encoding would be set to an unusual
value...
