            Bug ID: 26883
           Summary: printf should evaluate arguments _before_ printing
                    anything
           Product: poke
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: unassigned at sourceware dot org
          Reporter: jose.marchesi at oracle dot com

  Target Milestone: ---

In struct and union methods it is often useful to user `printf' like
his:

method _print = void:
{
  try printf "%i32d, %i32d\n", field_foo, field_bar;
  catch if E_elem { ... }
}

However, if field `field-bar' happens to be absent, by the time E_elem
is raised field_foo has been already printed.  This is a no-no.
