in reply to PGA Golf, Round 1

Here's my Hole 4, though I feel as if I must be missing something obvious, either incorrect in my answer or a different solution.
sub h2c{split//,pack"H*",pop} 123456789_123456789_
20 characters.

Update: I realize now that the answer is incorrect because it returns a string rather than a list. Thanks all. :)

Update again: Fixed the answer by adding the split.
