Not sure if that’s exactly what you want, but this works:

  binding1.eval("a + binding2.eval('b')") #=> 3

This is not 'merging' the two bindings, it rather opens the second
binding inside the first one.

Regarding Binding#eval, is there a specific reason why it can’t take a
block instead of a string, the same way e.g. Module#instance_eval does?
