it would be a very useful feature to allow overload on void and

alias i this;

Was the single conversion limitation specified by design, or do
we have room to expand it to allow for multiple conversions?
In C++ I used multiple conversions for a variant class and it
worked like a charm. The alternative was to manually specify a
named function based on the type to return, which is not as fun
to work with.
