I agree with tilly's Re^2: Useless <c>unless</c>. I don't use unless frequently in my code. The only place I use it is in the following construct - die $usage unless (@ARGV>0);. Every other place I switch to if as it is easy to read (at least to me)
That said, I would not advocate for removing this feature from the language itself. I feel removing a feature should be done if pretty much (subjective huh?) everyone in the user community do not use it (or) the feature has a significant overhead to the parser and has little benefit or other reasons that my mind cannot grasp. I am aware of unless traps. But I cannot blame the lang if i fall for it. I always have the choice to pick if. Regarding the otherwise suggestion i like it, if it is not going to span multiple lines. What i miss the most is something like this -
I know i could do
(or)
The last one is pretty much the same as otherwise but just that otherwise gives a natural lang feel -SK In reply to Re: Useless unless
