Paths are non-empty lists of identifiers in Nix.

>>> path # [ident # "yo"] Path [Identifier "yo"] 

Any attempt to construct the empty path throws an error:

>>> path # [] Path *** Exception: Nix paths cannot be empty 

Identifier is an instance of IsString:

>>> :set -XOverloadedStrings >>> pPrint $ path # ["yo","bar"] yo.bar 

Freaky quoted identifiers are fine except in the first segment:

>>> pPrint $ path # ["yo","b\"ar"] yo."b\"ar" >>> pPrint $ path # ["5ident"] *** Exception: invalid Nix path: [Identifier "5ident"] >>> pPrint $ path # ["5ident","foo","bar"] *** Exception: invalid Nix path: [Identifier "5ident",Identifier "foo",Identifier "bar"]
