Make strings iterable over their code points. I'm not sure why, but this also regresses perf: binary_trees - wren .......... 3290 0.30s 96.68% relative to baseline delta_blue - wren .......... 7948 0.13s 99.06% relative to baseline fib - wren .......... 3165 0.32s 95.90% relative to baseline for - wren .......... 8242 0.12s 96.00% relative to baseline method_call - wren .......... 5417 0.18s 78.74% relative to baseline Need to investigate. 2015-01-22 20:58:22 -08:00			`var s = "abçd"`
