1. Question/suggestion concerning printf()
Hello Rob,
if the number of values in the 3rd argument of printf() is smaller than
the number of placeholders in the 2nd argument, then Euphoria will raise
an error:
printf(1, "Text %d %d", {1}) --> not enough values to print in printf()
But if the number of values in the 3rd argument of printf() is *bigger*
than the number of placeholders in the 2nd argument, then Euphoria will
*not* raise an error:
printf(1, "Text %d %d", {1,2,3})
Is this intentional? Maybe if Euphoria would also raise an error in the
second case, this would help to find some "hidden" bugs in our Eu
programs? Just an idea.
Regards,
Juergen

Yes, it was done that way intentionally (about 14 years ago!).
I don't think it would be a good idea to change it and break
existing code. I feel it's better to be "permissive" about
output formatting. If the output looks wrong, people can
trace it back to the printf statement fairly easily,
and correct it.
