Using the modal command seems like it would be a good way to do this.

If we did add something like this, it probably wouldn't be limited to
"repeat", but should allow interrupting any handler. Something like
MacOSs "cooperative multithreading" comes to mind, in which case you'd
use "yield" to switch to some other "thread" or return control to the
main event loop. The problem with this (and the biggest problem with
MacOS threading) is that your scripts could end up spending most of
their time switching among the threads and checking whether to
continue instead of getting real work done. This wouldn't really be a
problem in your spell checker example, but would be if you tried to
use it for certain other kinds of background processing.
If you want to discuss this further, I recommend restarting the
"thread" about this on the xtalk list...
