Code review comment for lp:~zorba-coders/zorba/bug-966355

Also note that changes like:

  xs_integer pos = 1;

to:

  xs_integer pos( 1 );

are not simply stylistic: now that the constructors are explicit, the original line generates a compile-time error. It would alternatively need to be changed to:

  xs_integer pos = xs_integer( 1 );

that serves no purpose other than being verbose.
