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 -

doX() if ($cond) otherwise doY();

I know i could do 

if ($cond) {
  doX();
} else {
  doY();
}

[download]

(or)

($cond) ? doX() : doY();

[download]

The last one is pretty much the same as otherwise but just that otherwise gives a natural lang feel
