An alias just gives a different name for a symbol. It can't pass arguments for you or call a function and pass its result to another. So, while you could create an alias for Thread.sleep, you'd have to call it exactly like you'd call Thread.sleep - just with a different name. If you want to do something like have it accept an int instead of a Duration, then you need a wrapper function like you're already doing. Now, in core.time, dur!"seconds" has an alias named seconds, so if you're simply looking to reduce how much typing you're doing, you could have Thread.sleep(seconds(42)), or if you aliased Thread.sleep to sleep, you could do sleep(seconds(42)), but you can't do something like sleep(42) without a wrapper function. In any case, I'd suggest that you avoid passing around naked integers as time values. Thread.sleep takes a Duration specifically because it makes for clearer code and is less error-prone than using a naked integer (since a naked integer has no units). - Jonathan M Davis
