Original Ticket Information

Original Text

When a reference to a variable is used it should not be considered unused.

There is a common idiom when declaring an empty object which internal representation is a scalar:

    bless do { \(my $x) }, $class

or

    bless \(my $y), $class

Currently $x is reported as unused, while it is.

Follow-up Report (same date as original)

Workaround:

do { my $x; bless \($x), $class }
