ifn't
(programming.dev)
die unless $keyword == "unless";
I personally have a gut feeling of rejection for every language having the unless keyword. This is why I hardly know any PERL and Ruby for example.
I have mixed feelings towards Kotlin's takeUnless scope function (I nearly always use takeIf with a negated predicate) because my mind forgets the unless version exists.

Python already has this.
I shan't!
I can actually define this in TCL:
% proc ifn't {cond cmds} {if {!$cond} {uplevel $cmds}}
% ifn't false {puts 12}
12
% ifn't true {puts 12}
