At some point I did a prototype of “tuple completion”, basically you would write the arguments of a method in parenthesis (e.g. `(x, 1)` where x is a Set) and on tab it would show you all the methods with that type signature, with `(x,...)` being equivalent to `methodswith`. Completion would then add the method name in front of the tuple, making it a valid function call.

I didn’t find it that useful though (it was a bit buggy admittedly). But since `InteractiveCodeSearch` seems to provide everything you would need to do that kind of search it wouldn’t be very hard to implement it again in an editor.

You could have a lighter syntax, e.g `x)` alone would trigger `methodswith`, like `f(` triggers `methods`.
