Excellent reply and I'm now convinced too.

As a heretical aside, with the almost released new version of Build, you
can do something like the C-styled assert macro.

You can define a macro replacement pattern such as ...

  regexp <:assert\s(.*)::(.*):>   =
         if (!($1)) {writefln(`%%s:%%s`, `$1`, `$2`); assert(0);}

and then write in your code  ...

  <:assert result != 0::Bad result:>

which will transform into ...

  if (!(result != 0)) {writefln(`%s:%s`, 
        `result != 0`, `Bad result`); assert(0);}
