Surely this is not a common-enough requirement to warrant a special syntax.
At 80-columns, you can represent integers up to ninety-nine quinvigintillion, nine hundred ninety-nine quattuorvigintillion, nine hundred ninety-nine trevigintillion, nine hundred ninety-nine duovigintillion, nine hundred ninety-nine unvigintillion, nine hundred ninety-nine vigintillion, nine hundred ninety-nine novemdecillion, nine hundred ninety-nine octodecillion, nine hundred ninety-nine septendecillion, nine hundred ninety-nine sexdecillion, nine hundred ninety- nine quindecillion, nine hundred ninety-nine quattuordecillion, nine hundred ninety-nine tredecillion, nine hundred ninety-nine duodecillion, nine hundred ninety-nine undecillion, nine hundred ninety-nine decillion, nine hundred ninety-nine nonillion, nine hundred ninety-nine octillion, nine hundred ninety-nine septillion, nine hundred ninety-nine sextillion, nine hundred ninety-nine quintillion, nine hundred ninety- nine quadrillion, nine hundred ninety-nine trillion, nine hundred ninety- nine billion, nine hundred ninety-nine million, nine hundred ninety-nine thousand, and nine hundred ninety-nine. Surely that's enough for the vast majority of users, isn't it? And if you *do* need anything bigger (perhaps to represent the burgeoning U.S. national debt) then there's always some variation on: my $debt = +( 123456789012345678901234567890123456789012345678901234 ~ 567890123456789012345678901234567890123456789012345678 ~ 901234567890123456789012345678901 ); or even: my $debt = +( 123_456_789_012_345_678_901_234_567_890_123_456_789_012_345_678_901_234 ~ 567_890_123_456_789_012_345_678_901_234_567_890_123_456_789_012_345_678 ~ 901_234_567_890_123_456_789_012_345_678_901 ); if you like to group your thousands for better readability. With adequate constant folding, both of those are still compile-time constants. Damian
