- compile-allow-cond-fallthrough: parameter for a Boolean value indicating how to
compile a cond or case expression without an
else clause. If the value of this parameter is a true value,
then cond or case expressions are compiled
so that void is returned if no clause matches. Otherwise,
cond or case expressions are compiled to
raise the exn:else exception when no clause matches.
Note that this parameter is used when an expression
is compiled, not when it is evaluated.
- compile-allow-set!-undefined: parameter for
a Boolean value indicating how to compile a set!\
expressions that mutate a global variable. If the value of this
parameter is a true value, set! expressions for global
variables are compiled so that the global variable is set even if it
was not previously defined. Otherwise, set! expressions for
global variables are compiled to raise the exn:variable
exception if the global variable is not defined at the time the
set! is performed. Note that this parameter is used when an
expression is compiled, not when it is evaluated.
