Edit PowerShell script while it's running

Question

Apparently, editing a Linux shell script while it is being executed results in an undefined behavior.

What happens when you edit a PowerShell script while it is being executed?

Nothing happens. PowerShell reads in, and parses, the entire script before executing it — Mathias R. Jessen

@MathiasR.Jessen Is this behavior of all the PowerShell versions under all the supported platforms? — Hope

At least since 3.0, I can't remember (and don't have access to a copy of) version 2.0 — Mathias R. Jessen

PowerShell parses everything from top to bottom once and never goes back again.
Once it's in, it's in :)
If you need to reload as example, a PowerShell module into a current session you have to use the -Force flag.
