perl: the degree of freedom

be as you like if you write one liner program or quick hack. But be self-control if you want to write modules.

Be explicit.

For example,

my ($a, $b, $c) = (do something,
		do something2,
		do something3);

my $who   = do_something();
my $where = do_something2();
my $when  = do_something3();

I like python's intent policy in on sense. It is of value to use similar policy in using perl.
