Problem Statement

Some programming languages allow calculation of values at compile time.

Calculate   10!   (ten factorial)   at compile time. Print the result when the program is run. Discuss what limitations apply to compile-time calculations in your language.

Let's start with the solution:

my $tenfactorial;
print "$tenfactorial\n";

BEGIN
   {$tenfactorial = 1;
    $tenfactorial *= $_ foreach 1 .. 10;}


my $tenfactorial = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2;
