[REQ] JIT numeric conversion in mlr put, part 2 of 2

[johnkerl]

I'm splitting out this task to separate the put -S workaround part (#150) from a wishlist issue which would go a step further (but at the expense of a significant rewrite):

@gromgit so put -S handles your situation. But your JIT ask is spot-on: we shouldn't have to specify -S if no arithmetic is being done. That's a much larger codemod, and perhaps worth doing ... my uncertainty lies in whether the relative value of JIT-conversion over the FAQ-driven put -S workaround is worth the major rewrite. :^/

This will be addressed by the Go port.

This is already working in the Go port

Fixed in Miller 6.
