Warnings

It's a little too bad there's no way to avoid a warning when the variable we're fetching is not set ...

  You only recieve a warning? I get see an error. Most annoying!

    using 3.7.4 and getting an error as well. even testing for the existence fo a get/post var throws an error:
    {if ezhttp( 'myvar', 'get' ) } => returns false, but throws error
    the same with {if is_set( ezhttp( 'myvar', 'get' ) )}
    its a bug in my opinion..
Why not ?

It would be nice if the ezhttp operator could return all vars in the array specified. ezhttp(GET) would return all $_GET vars for example.
a forgotten parameter

If you need to check whether or not a get, post, session variable exists, you can pass a 3rd argument into the ezhttp call.
ezhttp( 'foo', 'get' ,'hasVariable' )
