Yes, it's slower (name below: ref). I guess if the string was much
bigger it could be a win:
array 0 wallclock secs ( 0.90 usr + 0.00 sys = 0.90 CPU)
@ 1111111.11/s (n=1000000)
array_bless 0 wallclock secs ( 0.94 usr + 0.01 sys = 0.95 CPU)
@ 1052631.58/s (n=1000000)
array_method 6 wallclock secs ( 5.79 usr + 0.01 sys = 5.80 CPU)
@ 172413.79/s (n=1000000)
native_method 1 wallclock secs ( 2.49 usr + 0.01 sys = 2.50 CPU)
@ 400000.00/s (n=1000000)
ref 0 wallclock secs ( 1.11 usr + 0.02 sys = 1.13 CPU)
@ 884955.75/s (n=1000000)
scalar 1 wallclock secs ( 0.56 usr + 0.00 sys = 0.56 CPU)
@ 1785714.29/s (n=1000000)
