> The ternary condition operator in Table API is named {{eval}}, for example: {{(42 >
5).eval("A", "B")}} leads to "A".  IMO, the eval function is not well understood. Instead
the "?" is a better choice I think, which is used in Java for condition operator. 
> It will be clearer and more literal understood, e.g.
> {{(42 > 5).?("A", "B")}} or {{(42 > 5) ? ("A", "B")}}
> If it make sense, I will pull a request.
