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?)
