in reply to Removing Trailing Whitespace: Multiple ways.

Hey, good idea. The unpack solution assumes the length of the string is 8. It'll get a bit slower if it's generalized.

Update: Strike that. unpack "A*" runs faster than unpack "A8" on my machine. Anyone have an idea why that might be? 

Benchmark: timing 1000000 iterations of unpack*, unpack8...
   unpack*:  7 wallclock secs ( 6.65 usr +  0.00 sys =  6.65 CPU)
   unpack8:  8 wallclock secs ( 7.40 usr +  0.00 sys =  7.40 CPU)
