I like a Nullable return much more than what I presented. I’ll have a look at how hard it might be to throw that together.

If all you need is to convert strings to integers, then it's quite straightforward and shouldn't take long to write. The problem with regards to something like std.conv.to is that it does a _lot_ of different types of conversions. So, while we definitely should have something like tryTo in addition to having to, it's non-trivial due to how much to does.
