It is possible to create a cond test-expr that also serves as the then-body, however, this means that the expression would be executed twice.
This seems to be ill advised in principle. Question: If it is ill-advised to create a cond test-expression that also serves as the then body, then what function is recommend? I am aware of the (cdr (or ... form. I am aware of the cond ... test-expr => proc-expr] form option. Thanks Don Green
