The benefit is, you are not limited to strings :P

But yeah, if it's just strings, you have not much benefit. However, I 
don't know what the cost is for parsing compared to the rest, it may not 
be too significant.

I like Ali's idea, make it a general purpose "putAll" primitive, goes 
right in std.range.primitives.
