Debugging ... little tweaks that perhaps can be useful

[Christian-Me]

Sorry ... not working (here)

node.warn('Foo speaking: ${config}');

And this as expected:

node.warn('Foo speaking: '+config);

and what I normaly do, nice object view but two messages:

node.warn('Foo speaking:');
node.warn(config);

this works but that's not the way to do it, right?

console.log('Foo speaking:',config);
