It seems that there should be a way to implement the following that only specifies the name list once instead of twice, but I can't figure out how to do it:
package MYPACKAGE;
[...]
my ($ab, $cd, $ef, ..., $yz) =
map { ... some function of $_ ... } ('ab', 'cd', ..., 'yz');
An example might be computing hash keys for field names:
my ($field1, ...) =
map { __PACKAGE__ . '::' . $_ } ('field1', ...);
[...]
... $self->{$field1} ...
How can this be done as...
foreach (qw(ab cd ef ... yz)) { ??? };
...preferably under "use strict;"?
Thanks,
A.C.
