verify-non-generic-switch

As with all compiler switch variables, the value of this variable can be t, nil, or a function object that accepts four arguments and returns t or nil. The arguments passed to the function will be the values of the safety, space, speed, and debug optimization qualities, in that order. nil is equivalent to a function that always returns nil and t to a function that always returns t. When the value is a function and we say t (or true) or nil (or false) in the text below, we mean that the function returns, respectively, t or nil.

If true, code is generated that an object of undeclared type is of the correct type when it appears as the argument to specialized functions like svref and rplaca. Thus the argument to svref must be a simple vector and, if this switch is true, code will check that (and give a meaningful error message). See Argument type for a specialized function example for an example. Note that generic has nothing to do with (CLOS) generic functions. The name long predates CLOS.

Initially true for speed less than 3 or safety greater than 1.
