Please?
Alpha knows about e.g. Framed Framed - Wolfram|Alpha
but fails to execute its own example Framed[x] - Wolfram|Alpha
Wolfram|Alpha doesn’t do this. It’s meant for natural language processing. It can handle some Wolfram Language code - mostly just the more common expressions that people tend to use.
If you want to execute Wolfram Language Code, I would check out Mathematica Online.

And we’re supposed to guess which those are?
There is no strict documentation for Wolfram|Alpha like there would be for a programming language. Instead there’s a list of example inputs for different areas of interest. This fits with how it was meant to be used.
I would not use it for Wolfram Language Code. It wasn’t really designed for that purpose. The Wolfram Language is implemented in Mathematica and Mathematica online.

That being by guesswork, it seems 
Thanks.
