I like that idea for its simplicity, and it would definitely be useful in
some instances.

However, I think the real world is slightly more complex. Checkpath would
at least want to know whether you were planning to read, write, or execute
the file (or possibly even dynamically load it as a DLL or equivalent).
These might all have different access restrictions.

By the way, writing a checkpatch function would be very OS specific. So
that leaves it wobbling on top of the slippery slope....
