OK, you're slow.

Apparently you tried to modify a read-only value
(a value that cannot be written to) in line 2 of cosik 
(whatever that happens to be). Apparently, perl 5.6.1
regards this as a Bad Thing.

>From perldoc perldiag

	Modification of a read-only value attempted
	(F) You tried, directly or indirectly, to change the 
	value of a constant. You didn't, of course, try 2 = 1, 
	since the compiler catches that. But an easy way to do 
	the same thing is:

	sub mod { $_[0] = 1 }
	mod(2);
	Another way is to assign to a substr that's off the end 	
	of the string.
