PowerShell has some great ideas, but I can think of quite a few things that can be improved in (or over) PowerShell: its abysmal speed, its verbose syntax, verb-noun structure which is much less useful than noun-verb would have been...
Now, is it "Stop-Process" or "Set-Process -Status Stop"? "Out-GridView" or, say, "Show-GridView" or
"Out-View -Grid"? The other examples are all technically legal, and other modules can and do have such inconsistencies.
With verb-noun, I can't meaningfully complete for the verb when I don't know it, I can complete for the noun if I know part of it. But I usually know the noun, so that's not so useful.
With noun-verb, I could get a meaningful verb completion and still be able to complete nouns - with some duplication of results, though I think there could be a way to have some semi-completion for the noun only. A semi-completion isn't useful in the verb-noun case, since the program can't guess the noun yet and different nouns may have different verb uses.
