The code above produces the warning message:
Found = in conditional, should be == at file line n.
If I change:
( $used_options{ $1 } = 1 and "\${$1}" )
To:
do { $used_options{ $1 } = 1 and "\${$1}" }
I still get the same warning message.

But obviously the message is wrong because there is no = in conditional.
