There's no compile-time closure happening here.  The LET is evaluated
at execution time (i.e., at load time).  No closure ends up in a FASL
file with the above code.  The DEFUN does create a closure, but not
until load time. (The definition of MY-LIST is presumably not
inlineable even if there is an INLINE definition prior to the above
code not shown in the example.)
