######## We start with some black magic to print on failure.
# Change 1..1 below to 1..last_test_to_print .
# (It may become useful if the test is moved to ./t subdirectory.)
BEGIN { $| = 1; print "1..1\n"; }
END {print "not ok 1\n" unless $loaded;}
use Foo;
$loaded = 1;
print "ok 1\n";
######## End of black magic.
Testing really isn't this frightening.
