# VALUES OF BEETA GIVE RISE TO DOM sub square_b { my $fOOooO = abs(shift())<<1; my $BarRRr = $fOOooO-++$fOOooO; $BarRRr += $fOOooO until ($fOOooO -= 2) <= 0; return $BarRRr; }

It passes all the tests, but that doesn't prove anything

We might say the same of this function:

sub square_c { my $x = shift; return 289; }

This passes the tests, but it is

*not*a function for computing squaresLet's write a function that examines the source code of another function

And returns true if and only if the code is for calculating squares!

Nope, no can do
