I've built a grid-widget where some of the columns use
editable-text-column-mixin so that the user can enter text into them.

Is is possible to have some sort of verification function run when the
input is complete, similar to the on-change event handler that runs for
the standalone editable-text?  I'd like to only accept valid lisp forms.
I could probably hack something up using the data-write-converter
function but that isn't called with enough information.

Any help would be greatly appreciated!
