in reply to variable processing and checking in one statement

You could do:

checkFn( $_ ) and doSthWith( $_ ) for $test;

which wouldn't interfere with surrounding uses of $_; and avoids referencing $test twice.

But I wouldn't unless the variable in question was a complex reference. Ie. a multi-level hash or array lookup.

"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
