In related question: does anybody here have experience/benchmarks/tests 
how/if is PackedString better (uses less memory) than String in parsing 
tasks?
I don't have that information, but in case it helps, look out
for splitPS - it makes the fairly common mistake of discounting
a trailing separator, so both A:A: and A:A split to ["A", "A"],
where the former should be ["A", "A", ""].  It does handle
:A:A and A::A correctly, so you can just wrap splitPS with a
function that may add a nilPS depending on the end of the input
string.
