I like print if m// partly because it reads better in my mind. I don't like m// && print because it is very idiomatic and no shorter than print if m//.

I like $var = shift || 'default' because it also reads naturally.

If you have to explain idioms to non perlers use the common programing idioms of if/then/else...
