The code:
use Module qw( this $that );
is the same as:
# BEGIN { } happens at compile-time
BEGIN {
require Module;
Module->import(qw( this $that ));
}
Read 'perldoc -q require' for more about how 'use' and 'require' differ.
As for what 'import' is, it's not a builtin function or operator. It's a
method Perl expects your package to have, and it defines how to import
symbols (such as functions and variables) from the package being used to
the package doing the importing.
You should probably read 'perldoc Exporter' to see how the general
importing mechanism works.
