SBCL readably prints BASE-STRING using array syntax
See:
CL-USER> (with-standard-io-syntax (print (coerce "hi" 'base-string)))
#A((2) BASE-CHAR . "hi")
This can cause issues when running the CLPM client from Lisps that don't understand this syntax. Should probably remove with-standard-io-syntax
in the client repl entry function.
