You could add '|| 0' to the Template code, wherever it does a numeric
operation. That may be quite a few places...
That would cover the case where the value is blank... but not other
non-numeric values, like trying to add 1 to 'sheep'. Another
alternative would be adding a function to replace all non-numeric
values with zero, and use that instead of '|| 0'.
Of course, this would all require getting to know the code inside the
Template modules.
FWIW, I agree with your point that Template itself should avoid these
warnings on behalf of the template authors. It already does so for
undefined values, so non-numerics seems like a natural extension of
that idea.
Here's an example of that function to replace non-numerics. The regex
may need some tuning:
sub replace_non_numeric {
my ( $val ) = @_;
if ( $val !~ /^-?\d*[.e]?\d+$/ ) {
$val = 0;
}
$val;
}
