If you were to operate on a string in a manner similar to a stream, you'd be 
operating on it as a range, and there are a lot of range-based functions in 
Phobos. But if you want to specifically parse a range of characters, then use 
std.conv.parse:

If you want to know more about ranges, then this is currently the best 
tutorial on them:
