IO::Prompt is returning an instance of IO::Prompt::ReturnVal, not a plain scalar value. Apparently this instance isn't boolean-ifying the way you expect (not that I disagree with your expectation after a quick initial read of the docs) and since it's not false you always get your first leg of your if executing.

Update: As a workaround you can explicitly stringify return $ans . "" or numify it return $ans + 0 and it should behave the way you want. Alternately explicitly test the value (e.g. if( shall_we() == 1 ) { ... } else { ... }).

Another way: Since you're using 5.10 there's always given: 

use feature qw( switch say );

## ... as your code ...

given( shall_we() ) {
    when (1) {
        print "In the 'if' statement: yes, we shall.\n";
    }
    when (0) {
        print "In the 'if' statement: no, we shant.\n";
    }
};
