perl -Mlib=. -MFoo::Bar -e 'print barfoo("blah");'

should work. '=' allows you to pass an argument to the module so -Mlib=. is the same as 
use lib '.';

which does an unshift for you but it does it at compile time and before the -MFoo::Bar happens.

Updated Broquaint makes a good point, Bar.pm must be the in Foo directory in . I was going to say also that -I. is wrong but it's not wrong it's just weird.

My first reaction was to suggest -I but when I checked it with 

perl -I. -e 'print join("\n", @INC)'

I didn't see . at the start of @INC so I switched to -Mlib=. Then I looked again and I saw that -I. does not not put . at the start of the search path, for my perl, it puts 
./5.8.3/i386-linux-thread-multi
./5.8.3
./i386-linux-thread-multi
./5.8.2
./5.8.1
./5.8.0
.

which will probably have the same effect. Where is it documented that -Idir will add dir and 6 other variations of dir to the search path? Or is that just some weirdness from perl on Fedora Core 2?
