The GF shell no longer has `put_tree -typecheck` option, and typechecking is done automatically when parsing.
The metavariable thing is a bit unclear: you don't get it when parsing "dim the light", or "switch on the fan, but you do get it when you `gt` after adding `switchOn` and `switchOff`.
```
> p "switch on the fan"
CAction fan (switchOff fan) (DKindOne fan)
> gt
CAction light dim (DKindOne light)
CAction ?3 (switchOff ?3) (DKindOne ?3)
CAction ?3 (switchOn ?3) (DKindOne ?3)
```
My hypothesis is that you don't get metavariable when parsing e.g. "dim the light", because even though `light` is suppressed in `CAction`, it still appears in `DKindOne`, so it gets to contribute to the whole tree with its string.
