Apoc4: 'when' blocks versus statements

[Bryan C. Warnock]

Why the double semantics of 'when'?

It implicitly breaks when used as a 'when' block, but does not as a 'when' 
statement.  It seems that a when should be a when should be a when, and a 
when being a when would be a win.  

The example given:

     given $x {
        warn("Odd value")        when !/xxx/;
        warn("No value"), break  when undef;

        when /aaa/ { break when 1; ... }
        when /bbb/ { break when 2; ... }
        when /ccc/ { break when 3; ... }
    }

could be written as:

     given $x {
        warn("Odd value"), skip  when !/xxx/;
        warn("No value")         when undef;

        when /aaa/ { break when 1; ... }    # No reason you can't
        when /bbb/ { break when 2; ... }    # explicitly break even when
        when /ccc/ { break when 3; ... }    # you'd implicitly
    }

or even:

     given $x {
        warn("Odd value")  if   !/xxx/;  # Since $_ is the localizer
        warn("No value")   when  undef;

        when /aaa/ { break if 1; ... }
        when /bbb/ { break if 2; ... }
        when /ccc/ { break if 3; ... }
    }
