I can use either the file-enable-sql-reader-syntax or the locally-enable-sql-reader-syntax / restore-sql-reader-syntax-state pair fine.  When I evaluate the same code in Slime with C-x C-e or C-c C-r, however, I get this error when defining add-customer:

	Interesting.  I tried this with SBCL and it worked.  Why would ccl64 behave differently?  (Code below.)
