What's wrong to type $_ if you want to print "`$_'\n" in your example? Etc. I don't see any problem with that as $_ is clearly states that's a loop counter. And let's don't even talk about map/grep/sort and schwartzian transform.

I don't think he sees that as a Problem. Only he thinks using it explicitly is not to his taste. I have a similar attitude: make it explicitly a new var if it is going to appear in the code.

Your example is perfectly OK.

TIMTOWTDI, really.
