I've saw this:

that you introduced:

valueWithInterval: aDelay

valueAfterWaiting: aDelay

which is a cool feature.

I only suggest that it could have shorter names.

Using: valueAfter: aDelay and valueEvery: aDelay

would make it look like:

[Transcript cr; show: 'Hello World!' ] valueAfter: 10 seconds.

In general, and when they don't introduce ambiguity or unacceptable vagueness,  shorter names help typing, make the autocompleter find hits faster and unload the memory bandwidth of our brains

Keep the great work!
