> The eval() Streaming Expression reads a single tuple from an underlying stream and looks in the expr_s field for an expression to compile and run. eval emits the tuples from the expression that it compiles. 
> This allows streaming expressions to write streaming expressions and have them evaluated.
> Syntax:
> {code}
> eval(expr)
> {code}
