In our project now, time.sleep appears undefined. Appears to have happened after upgrade to 8.0.6?

Our current build: **8.0.6-rc1 (b2019102814)**

So we can’t do:  
**import time**  
**time.sleep(3)**

Error:

Is this intended or a bug? Anyone else experience?

Thank you.

Sounds like a good thing. If you are using any form of sleep in a script, you’ve almost certainly screwed up. (Though there are cases where it is reasonable in a dedicated background thread. Use java’s Thread.sleep() for such cases.)

Do you have a project script library that’s literally called `time`? That looks like a namespace collision, not an import error; the object being referenced (that’s cut off) is probably a `ProjectScriptModule`.

Wow embarassing. Why did we name a project script as time?

Someone who did this is incredibly stupid, and it TOTALLY wasn’t me ;).

Thank you for the help!
