Right.  I don't expect PAR to find it, when it isn't there.  And I 
wouldn't mind a switch to enable such behavior; or a switch to make such 
a warning fatal; or both.  Or a switch to turn off the warnings, if they 
are on by default.

The case I have is very clear, there are no blocks or conditionals, the 
"use" will definitely be executed... and yet when the module is missing, 
there is no warning and no error, until you attempt to run the .exe just 
built.

I understand that "use" in an "eval", that pp wouldn't see those, or 
wouldn't want to do the flow analysis to try to figure out if they are 
actually used or not...  or "require" in a conditional might not get 
executed... the -c and -x options are good for some of those cases... 
but I didn't expect to have to use them for this case.
