Yes. Sometimes you want to conditionally test if a module can be loaded and
its import does not blow up.
It's a convenience function so it can be more easily understood what's going
on and we don't each write it a million different ways. require_ok() solves a
big chunk of the problem.
if( something something ) {
use_ok 'Foo';
# Here's one long hand way...
# require_ok 'Foo';
# ok eval { Foo->import; 1; } or diag $@;
# or maybe this, hope you remember that 1;
# eval 'use Foo; 1;' or diag $@;
}
Similar to how like() is basically a convenience for...
my $regex = qr/bar/;
ok $foo =~ $regex or diag "$foo does not match $regex";
If it didn't already exist, it could probably be argued that it's not needed.
But it's there and can be left alone.
