The particular syntax you're using there isn't valid PowerShell; a function can take a param block or it can take a parameter list in parens, but not param inside a parameter list.

How about something like:

In this case though, you're still in an empty file and most of what you're writing are either keywords or parameter names.

We get our completions from PowerShell and it doesn't provide keyword completions. Nor does it provide parameter name suggestions or untyped hashtable key/value suggestions. Basically, in the scenario you've got, things are still wide open, so there are no completions to provide.

Do you get completions on Get-<TAB>?

To me it looks like there is some random condition that's keeping PowerShell IntelliSense from providing results in a timely manner.

Look at this screencast I just recorded:

Typing get the first time brought up IntelliSense information right away. I didn't even have to hit the TAB key for auto-completion to appear.

Then, after deleting my line, hitting get-TAB didn't yield any result for a very long period of time. After that, auto-completion by typing get didn't work anymore and typing get-TAB kept taking a very long period of time.

Yes, this is a performance issue in the current stable PowerShell extension. It's improved in the preview extension, and we think the next release of the preview extension will have significant improvements here.

You can try the preview extension by uninstalling the powershell extension and then installing powershell-preview.

We've also committed to getting these improvements into the stable channel in January, so this should be improved over the course of the next few months.
