Quasiquotation for Rust Macros

Following Scheme, we'll provide a handful of operators to programmers to help them easily construct new syntactic forms (ie, output tokenstreams). These forms include:

quote!, for quickly creating new syntactic forms/tokenstreams
unquote, which escapes quote (following , from Scheme's quasiquote form), allowing users to perform general computation inside of a quote! invocation.
unquote-splice, which escapes quasi-quoting and then list-splices the result into the quasi-syntax term.

Where does the game take place?

The game takes place in one of the large, ruined cities of the world.

The city is ruined in "patches": some were burned down, some taken over by the weird, some destroyed in riots maybe? Nature reclaimed some, some is maybe weirdly missing.
Coastal city
One or two major rivers, mostly frozen solid
Sliced up into different turfs held by different people
There are underground tunnels in the city (who lives there?)
