The thing is, it's impossible to prevent the user from accessing
arbitrary functions in CL -- and things like SB-SYS:SAP-REF-*
precisely allow arbitrary pointer dereference.

Another issue is unsafely compiled code with violated declarations.
This could literally explode an unprotected memory system.
