The warning is important -- when it's important.  In my case, it was
important to avoid cluttering the exception log with spurious complaints
about the results of a process outside anyone's control.

In any case, that has zero to do with whether it makes sense to package
this behavior as a procedural abstraction.  Please note that I am *not*
arguing that Chicken's substring should behave this way, just that a
convenient implementation of the loose behavior does have use cases.
