//tvix/eval: + doesn't support appending a string to a path

Probably worth looking at how this works internally in C++ Nix, but I suspect it's just a string append:

nix-repl> /home + "lukas"         
/homelukas

nix-repl> /home + "/lukas"
/home/lukas

Maybe worth waiting until it is clear how paths will work in rnix-parser going forward.

Interesting side note: builtins.add is not equivalent to a: b: a + b:

nix-repl> builtins.add "a" "b"
error: value is a string while an integer was expected, at (string):1:1

nix-repl> builtins.add /home "/lukas"
error: value is a path while an integer was expected, at (string):1:1
