I disagree.
In a normal program, you may want to mix the two - use the safe
functions for untrusted input, the unsafe ones once you have already
validated the input.

Such a switch, if it existed, should only affect the *unsafe* version
of the call - this way, it would be possible to remove all chance of
corruption from a program at need.

Also, of course, the exceptions should be catchable based on the new
ghc 6.10 exception library (on ghc 6.10, anyhow)
