Re: Compression in Golf: Part I

[primo]

Just for fun, I decided to map out a bit of the region beyond pack's normal range. The results were... interesting.

Besides the panic: memory wrap and Can't localize through a reference, one other thing stands out: pack u78 uses a space as the delimeter. In cases where you can't quite get your code to fit into a u45 format (starting with an m), it's a viable alternative, and has actually been the shortest construction I've been able to find for more than one challenge.

The run of chr(0) from u83 - u95 is unfortunate, though. An eval'd string beginning with the null character seems to terminate immediately, without error, for whatever reason.
