Unless I misunderstand what you're asking for; you can do the
assignment multiple times with
different values:
$text = sub {
<<EOT;
Dear $person,
I know that this text is $adjective.
But I wish it could be...
EOT
};
my @subs=('Mom:not interpolates',
'Dad:maybe interpolated',
'Sis:who knows');
foreach (@subs){
local ($person,$adjevtive)=split ':',$_;
print &$text;
}
My technique will also
work for your number example (with everything
stored as a function). However it look slightly ugly:
$n = sub {1};
$m = sub {&$n*2};
$o = sub {&$m*2};
$s = sub {&$n." ".&$m." ".&$o."\n"};
print &$s;
$n = sub {2};
print &$s;
