Return::DataButBool 0.0.3

Perl's Zero-But-True ( 0e0 ) is a most handy tool (See String::ZeroButTrue). Return::DataButBool is a Perl module that expands on that idea by having a return value that has different boolean, numeric, and string values.

For example you could return a count of files processed (say 42 which is "true") but still say it failed in boolean context.

or you could return any false value ( not just '0' ) but still return true. The flexibility allows for all sorts of use.

SYNOPSIS

 use Return::DataButBool;

 sub whatever {
 ...
 return $ok ? data_but_true( $count ) : data_but_false( $count, $error );
 }

later in the code using this function:

 my $total = 0;
 for my $thing ( @stuff ) {
 my $rc = whatever( $thing );
 $total += $rc; # numeric value
 
 if( !$rc ) { # boolean value
 carp "Error happened: $rc"; # string value
 }
 }
