	The same problem occurs in 1.4.  Why would this work with SBCL from Slime and from both from the REPL, but not from Slime with ccl64?

Thanks,

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:
