If I were seriously looking at reading in a file lazily as a forward range, I'd look at http://code.dlang.org/packages/iopipe, though as I understand it, it's very much a work in progress.
There is an even more work-in-progress library built on that, but it's not yet in dub (this was the library I wrote for my dconf talk this year): https://github.com/schveiguy/jsoniopipe
This kind of demonstrates how to parse json data lazily with pretty high performance.
It really depends on what you are trying to do, though.
As for auto-decoding, yeah, it sucks. You can work around it with stuff like std.utf.byCodeUnit, but auto-decoding is a problem all around, and it's one that we're likely stuck with, because unfortunately, we haven't found a way to remove it without breaking everything.
I think there eventually will have to be a day of reckoning for auto-decoding. But it probably will take a monumental effort to show how it can be done without being too painful for existing code. I still believe it can be done.
