The compiler always does type inferencing for
simple-string
as if *default-character-element-type* was set to
character
.
For example, when you declare something to be of type
simple-string
, the compiler will never treat it as simple-base-string. Therefore calls like
(schar (the simple-string
x
) 0)
will work whether x is a simple-base-string, simple-text-string or simple-augmented-string.
