Greetings, +1 to the idea of gender neutral pronouns. However, the example confused half-awake me. Sometimes the antecedent is not always clear when using a pronoun, and the pronoun should be avoided. --- BEGIN SNIP --- Before: is( $total, $enrolmentfee_K + $enrolmentfee_J, "Kid growing and become a juvenile, he should pay " . ( $enrolmentfee_K + $enrolmentfee_J ) ); After: is( $total, $enrolmentfee_K + $enrolmentfee_J, "Kid growing and become a juvenile, they should pay " . ( $enrolmentfee_K + $enrolmentfee_J ) ); --- END SNIP --- Who is to pay? The kid? The guarantor? We also need to avoid antecedent confusion. “Kid growing and become a juvenile, they should pay” might be better worded “A child growing and becoming a juvenile has a fee of “. Because frankly, a library doesn’t care who pays a fee. They only care that a fee charged for a particular reason is paid. This would also clarify that it is the change of class, not a particular gender that affects the fees, because “[i]nappropriately using a particular gender can cause confusion, leading someone to believe that code operates differently based on the value of borrowers.sex, for instance.” Just some random morning thoughts.
