;;; In function MAKE-KEYWORD, checking types of arguments SYM.
What does this note mean?
That means a possibly expensive type check for SYM was inserted at the beginning of the function. In this case it is possibly ensuring that SYM has the right type for STRING
I hope that in addition to checking the types of the arguments, it
also generates the code to do the required computations... ;-)
Sure :-) I thought the warning is important because of the expensiveness of the checks, which may slow down critical functions.
