bugs in example:
## Example 3a: Calculate by assigning directly into fields...
my $A = $t->col->('A'); ## This column will be modified
my $B = $t->col->('B');
my $C = $t->col->('C');
foreach @($t->all()) {$A->[$_] = $B->[$_] + $C->[$_];}
## Example 3b: Same calculation, in a single statement:
foreach @($t->all()) {($t->col('A')->[$_] =
$t->col('B')->[$_] +
$t->col('C')->[$_])};
