Re: Free format question on D specs

Stylistically I have wondered why we ever use Yes/No'; we already have 
the very clear *on & *off.

Why not a meaningful named indicator for each condition being tested?  
Something like ItIsReady, WeMayCall, or just Flag1, Flag2,etc.

giving us code like:

    if ItIsReady;
      SendInvoice();
      ItIsReady = *off;
    endif;
